wow, Brook, i was concerned there. when yer cat was going after the cable, at first i thought she was going to use the amp for a scratching post. that was close
New filter caps and the regular stuff. It had been sitting for many years. We are going to test a little more then see if we need to tame those highs and get a little more midrange. Also will probably attend to the speaker and try some others.
This is what amp tech wrote: Made a new tremolo roach with an LED instead of a neon and hand selected an opto with a good range/response. Trem is much deeper. Also made some tweaks to the surrounding circuitry to make things good as possible. I know you like your trem. Tremolo tube is currently a vintage mullard. I would recommend pulling that and installing something cheaper and use the mullard elsewhere. No audio goes through the tube, you just need something strong enough to wiggle. Great place for microphonic Chinese junk. I put a bit of tape on that shield incase you wanna pull it. Speaker has a rattle when you hit a loud bassy note, so might need a recone or a new speaker. Tony’s more versed in that stuff than me… Otherwise, all the normal stuff. Fuse was too big, cleaned and tightened stuff, new caps, few new resistors, backup diodes on the rectifier. Power tubes are a little mismatched, but seem fine. Right one might be starting to go microphonic, but doesn’t seem too bad yet. This amp does need to be rebiased if you change power tubes. I made the ground switch a boost, quiet position is stock. Can also pull v1 for some more boost if you don’t use the normal channel, or you can try the channel jumper thing, unlike the deluxe reverb.
Bro I was freaking out with your cat! You are much more trusting than me haha
She is funny! I just try to hold it together. Thanks!

Luckily she has not decided to shred my amps!
is there any information on the speaker installed in the amp ?
It's pretty close to stock. Had been replaced a long time ago.
That’s a cool guitar.
when you said you got it from being serviced, what was done on the amp? This is a true 1964
