First I have to learn how to solder tube pins (even at my age), and now I have to learn how to read too? Damnit. Maybe time for me to switch to an easier hobby, like rebuilding nuclear reactors or something. :laughing::stuck_out_tongue_closed_eyes:
Just because somebody is having a bad day doesn't mean you have too. :)

Hmm maybe I should know my date codes better before speaking but, “6529” I thought was 29th week of 1965. The new arrival is marked “6038”.

It's right, just literature states Bendix stopped manufacturing in 1964. And if that's true (---->IF <----) then I'm wondering...who built that Chatham? The thinner micas add some fuel to my question.

Third time is a charm, I think. This Chatham from 1960 isn’t damaged and tests well at 90/90 %. My previous one with a cracked mica was 1965. I also notice the 1965 has thinner micas

side note: does anyone have an extra tube tester laying around they are willing to part ways with?

I have a Hickok 752, an 800A, and a Weston 981 Type 3 sitting here just waiting for some love. The 752 has been restored except I'm not getting any meter movement on the GM test. It's not the meter -- pretty sure it's the main test selector control. Have a donor unit here for an organ transplant, just lacking the motivation to swap the controls out. :laughing: The 800A is in good shape mechanically, but haven't finished up the case yet. And the Weston hasn't even been looked at, although I already purchased the capacitor set for it. Sigh. Seems to be so much to do when you aren't working. LOL!

Nice! I wish I had the space for a workbench or even a basement or garage. Then I could attempt to restore a unit and try to calibrate it.

The 4 guys that were left at the factory to assemble whatever they could from leftover parts, and then shut the place down. :smile::sweat_smile:

LOL! My workspace is in a spare bedroom, if you can even call it that. It's more about the size of a closet, except it actually has a closet and is therefore technically a bedroom. :laughing:

Ah yes, that’s why communion wafers were used.

There's so much out there, and ANYTHING is better than stock.. (except GE tubes..do not get GE) I suggest grabbing a beer or two and going back 50 pages and start reading.
How come he doesn't have to start at the beginning?!?!:sweat_smile::stuck_out_tongue_closed_eyes:

Start from page one and grab a side getter GE for beginners!! :stuck_out_tongue_closed_eyes: :stuck_out_tongue_winking_eye::stuck_out_tongue_closed_eyes::upside_down: Joking but..not joking.. Here's an old pic of one of my first ever tube rolling experiances.... many moons ago.. (two GE's and a Darkvoicce...OH MY!!) L M F A O .. :D :D

The glow on that GE power tube looks like some out of control reactor core. Damn.

I will say I'm extremely impressed you survived that. Lesser men would have sold the DV immediately and bought a solid state amp. :sweat_smile::joy:

For anyone looking to try out the Sylvania 6J5GTs (link) - NOS pairs, appears to be gray plates. (you can find used ones for cheaper.) :L3000:

Just curious what is the longevity of this amp? One guy can sell me a 3 old one. He says it was barely used, and yet I see a guitar in the background.
What would be a fair price for it, assuming he paid 220USD for it? Also, is it a good idea to buy a second-hand amp (might have to replace tubes right away for it).

I may about to say something sacrilege, but I am liking the cheap metal tubes better. Was rolling both the Sylvania 6J5GTs and these Philco Metal 6J5. They Sylvanias are solid all around tubes: they are non fatiguing and do everything solid (nothing that particularly stands out). But to me that strength is its weakness: they sound boring when compared to these metal tubes - which sound more alive and musical (nice sub bass delivery also). YMMV as always but - don't underestimate these cheapy metal tubes. LOL.
