Tube Amp Archive

Thanks. I will call the tech and tell him the news.

Well, it was the transformer after all. My tech installed reverb transformer from Twin reverb, it works now, sounds good, but I'm not sure if that's OK in the long run. What do you guys think?

Thanks!

Thanks guys. If tank is the problem, is this one a correct replacement?

My 90's fender reverb unit doesn't have reverb anymore, only dry signal. I checked the tank, looks good, swapped tubes, didn't help, so I'm taking it to service. So, just in case I'd need an output transformer, which one would you recommend? I found this one, it says it's for 6g15, but I'd like to k...

Got it, thanks guys!

at the moment, it's a 30 watt, 2x5881 amp, (sort of cross between fender super 5d4 and magnatone 260), but it has 4 output sockets (long stroy :)). Plate voltage is around 400V. If that's at all possible, I thought I'll just put four 6v6 in it and adjust the bias circuit. Kinda love the 6v6 tubes la...

Is it ok to use four 6v6 tubes with ClassicTone # 40-18088 transformer?

Does anyone have this amp? I'd like to know the individual speaker impedance for this amp, schematic says 16 Ohms: http://schematicheaven.net/fenderamps/cbs_70w_mstrvol_pullsw_super-pro-bmstr_rev.pdf But I have four 8 Ohm speakers (they look stock, blue fender label, CTS I guess) in my amp, parallel...

All clear, thanks Martin!

I would just like to hear how does it sound. :) Here's that post from tdpri: "Here's How: Ground both 12AX7 cathodes (pins 3 and 8 ). After the pair of 68K resistors, connect to where they intersect and are joined - a .022uF capacitor between them and the input grid at pin 2. Then - also from pin 2 ...

Hello, I would like to try grid leak biasing (.022 caps go to grids, grid leaks are 5M and cathodes are grounded) on both preamp stages in my homemade 5f1 Champ just to hear how it sounds. As cathodes are grounded and if NFB stays in place (on the second cathode), it's grounded too. Do I leave it as...

any love for this mindblowing guitar player from another galaxy?

It looks like the NFB resistor and output grid leak resistors are not soldered?
