Description
Hickok 6000A Mutual Conductance Tube Tester
Calibrated and Near Perfect Specs in a new custom case and a
NOS Jewell Meter
calibrated for the Hickok 6000 series tester @ 100 microamperes and 1165 ohms. Very smooth slow movement with no banging at either end, and easy to adjust to the line. A NOS 100uF Panasonic capacitor was added to the meter on separate lugs.
The Achilles heel of all Hickok tube testers is the meter since most are out of spec simply due to aging and corrosion, or the glue holding the pointer has failed thus giving inconsistent readings. This new meter is a huge improvement over the extremely bouncy original Hickok meters.
New Custom Case
with an oversized top cover (as compared to the original). The top of the case can be closed with full size socket savers left in place and the plate cap wire tucked away in the tube island. The case is solid ¾” wood with all new heavy duty hardware and is painted a textured black.
This is a late model Hickok 6000A and the serial number on the original case number started with 391, and tube chart is dated
1966.
The tube chart is too big and binds at either end. Hickok had a solution for this problem which were thinner wood rollers, but they are not on this 6000A. Possible it could be fixed to operate better than it operates now.
A
NEW
SS 83 installed
constructed with precision wire-wound Clarostat military spec resistors, Fairchild rectifier diodes, and ON Semiconductor Zener diodes in a Ceramic Base with gold plated pins. A Nos Sylvania 5y3GT rectifier is also installed.
The SS 83
requires less power draw on transformer and generates less heat. This 6000A has an original 350 ohm rheostat for the line adjustment which makes the SS 83 a practical replacement.
The
SHUNT
was cleaned and
CALIBRATED
in order to give it consistency. Most of the shunt potentiometers on any Hickok tester, unless cleaned, have become fouled up with the original thick lubricant that has hardened over the past 50 years making the shunt dial very inconsistent. Very important on a tester that relies on the shunt for Gm testing to be as consistent as possible.
A very small movement of the shunt dial can make a big difference with the readings. This shunt is now right on the money with the factory calibration.
I can hypothesize this 6000A was used very little to not used at all due to a defective Hickok meter. The tube island tested all tubes with no trouble. In particular the 7-pin min and the 9 pin noval tested the tubes with no issues and look as good as NOS. Pic 18 shows a close up the 7-pin min and the 9 pin noval sockets.
Note:
the 9 pin socket has a
center 10th pin
.
The 9 pin noval socket with the tenth pin is also known as a B10G or E10-73 socket.
There are a few tubes such as the 6C9, not many, that need that pin in order to test. Putting a socket saver on that socket using a screw and nut can be tricky without losing the 10th pin connection. In most case that 10
th
pin is not needed.
This 6000A is exceptionally clean inside with little signs of any corrosion or that white powdery buildup normally seen on most Hickok tube testers.
Included is a DVD of the operation manual that includes tube data, obsolete, foreign, and domestic; voltage specs; schematic; additional information on maintenance, and Hickok's calibration procedures for the 6000/A.
24 PICS THAT ENLARGE ABOVE
Voltage SPECS that can be seen in the pictures below. All tests were done with the correct shunt resistor to duplicate 1,000 Ohms/Volt Meter.
Picture 3 shows the AC signal voltage 2.55 SPEC is 2.5 +- .2
Picture 4 is the plate voltage of 150.0 SPEC is 150 +- 5
Picture 5 is the screen voltage of 133.4 SPEC is 130 +- 5
(Hickok’s calibration procedure for the 6000 has the spec at 135.0 which is incorrect. That is the spec with a 20000 ohms/volt meter and it has it the same 135V for the 1000 ohms/volt meter which is a typo and it should be 130V on 1000 ohms/volt meter which is the same on every other Hickok tube tester, and Hickok designed military tube testers such as the TV-7).
Picture 6 shows the low screen voltage of 56.0 SPEC is 56 +- 3
Picture 7 is bias voltage at 100 which is -39.9 SPEC is -40 +- 1
Picture 8 is bias at 22 which is -3.0 SPEC is -3.0 +- .2
Picture 9 shows the filament voltage with the tube in the socket at 6.5 which there is no SPEC for in any Hickok manuals, but critical to get accurate test results. Many Hickok testers can be calibrated, but the heater voltage drops below 6 volts when a tube is in the socket causing inaccurate results and may be signs of a weak transformer.
Picture 10 and 11 shows a 6L6 calibration tube with Gm of 5750/5800 being tested with results of 5750 right at 85 ½ on the original mark on the dial.
This 6L6 on average tests for Gm at 5750/5800 on other Hickok testers, and has tested as high as 6500 on a calibrated Hickok tube tester and as low as 5200.
Pictures 12 and 13 shows the same 6L6 calibration tube with Gm of 5750/5800 being tested with results of 5750 which is just over the edge of 92 at the original mark.
Picture 14 and 15 shows a 12AX7 calibration tube with an average Gm of 1400 to 1900 on several calibrated Hickok testers being tested with results of 2100 right at the original Hickok mark at the edge of 72 which is the mark on the dial.
The 9/10 pin noval socket is tight and tested the tube with no issues. The 9 pin noval socket with the tenth pin is AKA a B10G or E10-73 socket.
Picture 16 shows a 6AQ5 with Gm of 4600 to 4900 on several calibrated Hickok testers being tested using the 6K mark on the dial with results of 4900. The 7 pin socket is tight and tested the tube with no issues.
Pic 17 shows a 6JE6 being tested using the plate cap in the one of compactron socket
s that could not be tested on a 6000 without an adapter or an additional 6000A tube island.
Pic 18 shows a close up the 7 pin min and the 9 pin sockets.
Note:
the 9 pin socket has a
center 10th pin
. There are a few tubes such as the 6C9, not many, that need that pin in order to test. Putting a socket saver on that socket using a screw and nut can be tricky without losing the 10th pin connection.
The marks for the 3k, 6k, and 15K are right on the money using the original marks.
Note:
the 6K mark and where I had the dial lined up when testing the 6L6 which is at 65 ½. The actual mark looks to be closer to 86. Right on 86 the reading was 5500 rather than 5750.
This is a 6000 series tester that uses the shunt to determine Gm values rather than a set switch such as the 533a, 752, 750, etc., thus not as consistently accurate due to the use of the movable shunt dial to determine Gm values and why if a new mark is to made on the dial, it is better to put it directly on a number rather than between so it is easier to set the dial on the correct mark. Even though the shunt was cleaned and calibrated, this and any other shunt can still be erratic at times meaning it is not a laboratory precision device.
Checked all the filament voltages and they are all working at proper levels.
The shorts lights all work.
Please know what tubes this 6000A can test since it cannot test the older 4 and 5 pin tubes without another tube island or adapter. This 6000A has the 9 pin and 12 pin compactron sockets. Please know what tubes this 6000A can test before buying.
I have described what this tester is and provided as many pictures possible and this 6000A cannot be returned for any reason and is sold as is for parts or repair. This 6000A is sold as is for Parts or Repair. I will insure the tester in shipping at my expense. Security Measures are in place that will show if this tester was tampered with in any way. If you are uncomfortable with anything stated DO NOT BUY THIS TESTER!
This 6000A is sold as is for parts or repair and is listed as is for parts or repair. Why Parts or Repair? Some scammers get away with abusing eBay's buyer protection, the age of this device and the nature of vintage electronics, potential user error, and many other things that are out of my control. So do not send me a message asking why for parts or repair? This only means you did not read this and I will not respond.
I have many years of experience working with Hickok tube testers which include working in a certified Hickok warranty repair shop where I did all the repairs under warranty, and repairing Hickok testers that were no longer under warranty. I was replacing Hickok meters in the 80s and for a small fee as a favor for customers and that time building or repairing meters was much more difficult.
The pictures are part of the description so please enlarge them and take a look for better details.
The test adapter and calibration tubes are not included.
Will be packed in an 18x14x12 box weighing 20 pounds.
Several Options Available for Shipping.
If you have any questions please ask before buying.
I include insurance for shipping
I now offer
1 free calibration
within 3 years of purchase as long as you pay the shipping and for any parts that may be needed, e.g. a new 83 mercury rectifier. Please keep the calibration sticker on the tube tester, or remove and attach it to a separate piece of paper and keep it so I can refer to it upon calibration request.
OTHER HICKOK TUBE TESTERS READY TO GO!
Other Hickok Tube testers I have to sell but not yet listed: 539C, 752, 800, several 6000 series, 533A one silver and one gold, and 600A. Most are calibrated and ready to go, but a few require new case. This 6000A is more expensive than usual due to the new case and the new meter and the tester is about as close to NOS as you can find. I have other 6000 and 6000A testers in the original case with the original meters that are clean and calibrated that I will sell for considerably less. If yo would like a price on any other model mentioned just send me a message.

If you make an offer and it is accepted payment is expected within 4 hours unless a previous arrangement was agreed to.
Shipping
There are no hidden charges for handling or materials. You will pay the actual shipping rate per shipper. All tube testers are insured for full value at my expense and packed extremely well and pictures taken of packing procedures.
Terms of Sale
AGREEMENT
Must read and agree to terms below:
Please note and understand that there are no returns on this tester and is sold strictly for parts or repair.
All sales are final and this Hickok 6000 tube tester and is sold for parts or repair only due to scammers and the nature of vintage electronics that can easily be damaged by user error. I am creating my own web site to sell tube testers, and tube tester accessories such as new meters, which is cheaper than being scammed. I started the site once and will be doing so again under the name "Hickok Meters" since anyone who owns and uses a Hickok tube tester is eventually going to need a new meter. The delay is having to learn Word Press to complete the site.
If you have a legitimate problem upon receiving this tester such as the 83 rectifier was broke in shipping, which rarely happen, but can in high altitudes shipping internationally due to the vacuum and increased pressure, or something got broke in shipping, please notify me immediately. Immediately means within a few hours of receiving it not 36 hours later or 2 weeks.
The transistor function (if applicable) was not checked on this tester.
This tester is over 50 years old and should last another 50 if used and maintained properly, but if directions are not followed and someone tries to test a shorted tube e.g., any tube tester, or meter, can be destroyed in a second. I am not responsible for user error. You are expected to read the manual and understand what you are reading. You need to familiarize yourself with the tester and how it functions. Please take the time to do this since it could save you a lot of grief such as pressing the Gm button when testing a rectifier. It is an easy mistake to make and why you need to be careful when using this type of equipment. If you read the manual and use the manual while using the tester until you become experienced, you should have very few problems if any.
Also, the same tube tested on different and also calibrated testers will usually give different results on each tester. Please do not expect this tester to have the same exact results of a tube tested on another tester. If you expect that this tester will test the exact same Gm because it is also calibrated and all within specs, then are disappointed and want to return it because it tested a tube higher or lower than you expected, do not buy this tester. You are looking to buy something that does not exist and I do not have the time or money to waste on non-issues and unobtainable perfection.
I am not responsible for teaching you to use this tube tester or paying anything if you take it to someone for anything.
This is a 6000 series tester that uses the shunt to determine Gm values rather than a set switch such as the 533a, 752, 750, etc., thus not as consistently accurate due to the use of the moveable shunt dial to determine Gm values.
Thus this is not a laboratory tube tester and if you expect laboatory tube tester results from this 6000A tube tester; do no buy it. This tube tester, due to its age and the nature of vintage electoronics, is sold as is for parts or repair. If the tester is damaged in shipping do not try to use it but rather contact me and a claim will be filed with shipper and being refunded will be contingent upon whether or not the shipper honors the claim. I take pictures of packing the tester and it should not be damaged in shipping and packed extremely well with fragile labels.
