I like your setup actually..The TT-1 is my favorite of my testers..I think the 539c is liked because it gives generous readings on most functional tubes depending on where you set the scale range and that looks good for a guy selling tubes on Ebay. I just wish it had the additional 120vdc when testing KT88s like the TT-1 has,between the cathode and plate.
Honest amplification is better than excessive 2nd order distortion anytime.

who knows what I did with that. That was so long ago I probably gave that away ;-)
Those things are real cheap and flimsy anyway, hehe.
Can't wait to finally have the time to re cap it and replace the diodes. I will do that first and see if that stops the power sag on the heaters that happens when you try to test tubes.
Then, look over the resistors. None look cracked or burned, and it is super clean under there. I'll post a thread when I finally get around to it.
When it fell off the bench it cracked open like robin's egg and spilled its guts all over. I think I managed to put all the parts back inside....though I may have missed a few pieces.
