Received this as a gift a couple of days ago. :D Did the usual google search for all the schematics and tube information. I tested with a couple of 6l6's and an el84 and it seems to work fine. I did notice that most of the resistors are above 10% tolerance. Would it be a good idea to replace all components that don't meet the 10% tolerance threshold? There aren't many... :D

I have an old one around here myself. I'm not too sure how accurate it is. I do remember it not being able to check for one aspect (leakage or short), but it does seem to give me a good enough reading on how strong a tube is. I've got a bunch of nos and uos tubes sitting around from when I had my Mesa amp.

Sorry I don't have an answer to your question. But those things sure are handy to have around if you're wondering how good your tubes are.

Look at the forth band on the resister and see what the tolerance should be.
