I posted this over at the TDPRI about a month ago, but thought the amp-heads over here might enjoy my foibles...
I received a new Champion 600 from my son as a belated birthday present!
Curious wondering what tubes were in it, as under another thread (on the TDPRI) I had read they were sometimes using EH and Sovtek instead of Chinese. Well, the tubes came out easily, even without taking off the back: The 6V6 was "Made in China December 2007" however the preamp was a Sovtek 7025/12AX7WA, pretty good.
Power tube went back in easy enough...CANNOT get the preamp tube back in...check pin orientation with inspection mirror..nope, won't go. Take back off. No better. Harumph! Down to the workbench, take out the chassis, STILL won't go in. Tube socket looks like two-part, start to unscrew, only the base for the shield comes off, but now I can see the pins well. All are lined up, won't go in! Nothing is bent, all the contacts are there. Well, if I can only do this once, open up the cache, and grab a NOS Amphenol 7025. With great effort, almost to the point of breaking the tube, it slides home.
Thats some tight tube socket!
Ok, its open, grab an RCA 6V6GT while I'm at it, and get 'er all back together.
Ahhhhh, very nice! Even better through my Tremolux cab with a Reverend speaker in it.
This might be the beginning of a beautiful friendship...if I don't have the urge to change the preamp tube again!
