Vintage KNIGHT TUBE TESTER model 83XY142/ 83YX143, , ALLIED RADIO CHICAGO

Description

From closed radio shop... plugged in and powers up, turned to line adjust control and needle went up.  No further testing done.
these often need a capacitor or cleaned or calibrated ....   being sold as-is, final sale.
has the original book, that tells you how to construct the unit.  also roll chart is missing....
there is pages from a 600 series that has the charts, I am guessing he felt it was same settings?  not sure if all the pages are there...
has lid.  has cord.     also note: has those two additional sockets mounted on it, (top right)  not sure if they are tube straighteners or what....?
so this needs some TLC , you might need a roll chart or original book and unit may very well need gone over.
as-is, as found, final sale.   thank you
