[TV MAN]

Hi all! I am getting ready to set up shop again for the winter and tackle some projects. I decided it was time to upgrade to a better tube tester. "Want" or "need", I am not sure of - yet, but this is an instrument I will be using frequently over the years, so I settled in for a Hickok 600A from Ebay. Didnt get a super deal, but nowhere near what I have seen them sell for either. It wasnt in the budget to get a calibrated, ready to go unit, so in typical "me" fashion, I found something that appeared decent and was described as "working but needs calibration". Well, as usual, NOTHING I get from Ebay actually works properly without some TLC, and this tester is no exception. So, in saving the extra $300+++ I could have paid for a properly working unit (which may ALSO need overhauled), I am ready to get out the tools and get this working right!

   

This is a nice, clean "estate" find (per the description). It does power up and test tubes. Overall, it does appear to be a nice tester. I chose a model 600A because is seems to be the "Chevy" of the tube testers, and seems to be support and parts out there.
 I downloaded a manual from BAMA, and found calibration instructions from Danial Schoo (from 9-2006) and a few bits and pieces here and there. This will surely be a familure sight to many.

This is a completely different instrument than my Eico 625, and the manual I downloaded seems a little vague in details, in which I am sure many here will be familure with. So, I will have some basic questions. I welcome any tips, how-to's and comments as I attempt a restoration. In not seeing any other (recent) threads on restoration of a 600A, I thought it might be interesting to get one going.
