Tube Amp Archive

I did swap tubes and the pots seem to measure okay. The voltage is there as well. I'll test the caps this afternoon. Thanks for the advice!

Hey Mark! The trem jack is a rca jack for the footswitch. By the way, I still want to hear your amp!

Just wondering if anyone out there had any advice on this. I can't get the vibrato working on my Fender 5f11. I've done basic continuity tests but no luck. Any advice would be greatly appreciated!

Yeah, I would consider a trade. I have to quit playing through it because I'm really starting to like it. I'm not a collector and I think the best thing to do is leave it the way it is and let the next owner decide what to do with it. some of the tweed needs to be glued back down on one side and it ...

I picked up a 1939 Hallicrafter shortwave radio a few months back for $40 just to tinker with and soon realized that I didn't need a shortwave radio. I also thought about the ipod idea just for laughs, but the cabinet is so cool, I thought I would build a tube amp with it. I'm still trying to decide...

Would it have been on a sticker? If so, it's long gone. The tube chart shows KA for dating and the s...

I was wondering about the selenium rec. What is it for? Vibrato? Also, can you run these old amps wide open with the original OT?

Thanks for the advice. I'll post some pics. It's a 5F11 with the original jensen speaker. Funny thing is, my wife is not sure that it's worth the 200 bucks that I paid for it.

Hello all! New member here! I just purchased a 61 tweed vibrolux in pretty decent shape. It looks all original with the exception of one metal-film resistor(between the first two filter caps). also, all tubes have been replaced. The tubes glow and very little sound comes out. The original Astron fil...
