Dynascan B&K Precision 747B Dyna-Jet Dynamic Mutual Conductance TUBE TESTER

Description

Dynascan B&K Dyna-Jet
Dynamic Mutual Conductance Tube Tester
Model 747B  ~ ~  Includes Replacement Instruction Manual / Tube Setup Chart
Exactly as shown. Acquired at a local auction, so I do not know its history.
I only own two tubes, and tested each of them with no problem. No further testing done, as I am not knowledgeable enough to know what else to do.
Please look over the pictures (zoom in for very detailed views).
I can say that it is missing the "plate cap, grid cap or cathode cap cable", #25 on the chart. These seem to be readily available on ebay, or probably an item that most electricians would have laying around.
It does not have the Tube Chart (#24 on chart). However, the included manual has the tube set-up charts.
I notice the black plastic end-cap is missing on the right hand side of the row of switches (see last picture above). This does not seem to affect anything except cosmetics.
Looks like a 3/8" hole drilled through name plate on outside bottom of case. I have no idea what thats about.
Besides items mentioned, cosmetically in pretty good condition. Latches have some rust, but work fine. Handle/strap in good shape.
Since the tube chart was missing, I purchased the "Instruction Manual / Tube Setup Chart" book (shown in 9th picture, yellowish cover). Spiralbound, 9x11 inches, 65 one-sided pages. Weighs just over one pound.
Largest dimensions of "suitcase" 20 1/2 inches wide, 12 1/2" tall, 5 1/2" deep, and weighs 11 1/2 pounds.
Since I cannot fully test this, I am offering it AS-IS,  as pictured, and as-described.
Please be sure of your application...... No returns based on buyer's remorse.
Choice of insured Fed-Ex, parcel post, or priority mail to any US zip code.
NOTE: depending on your location and the shipping rates, I may switch between the 3 shipping options, unless you notify me that you need it one way or the other.
Any questions, please ask before bidding or buying.
Thank you for looking!
