Re: #34/#36/#39 scheme

Nice work ! What schematics did you use for this ? I was going to build one with a jubilee one channel and an AFD the other Frank Levi sent me the scheme of preamp stock/#34 modes. On this video the sound isn't so cool because they used Fender Telecaster for demo, but i used Gibson LP Classic live ...

Re: #34/#36/#39 scheme

Jubilee is not so trebly as #34 and other mods #36 and #39 has another tone compare to 2555.
Jubilee has a sweet tone but those mods have a little bit different.
Many people do these mods and it works -
for example

Re: #34/#36/#39 scheme

I have one more amp, AFD100, there is a correct loop, right to the power amp. I can use it with that preamp.

Re: #34/#36/#39 scheme

A quick look at the Amp circuit you mention tells me you are heading for a disaster. :blackeye If I'm looking at the right schematic the Fx loop returns to another triode stage and then the tone tree then into PI and power tubes. The result will likely be buzz, hum, crackle and a lot of squeal if y...

Re: #34/#36/#39 scheme

The schematic is ok but there are a lot of things between rows when you building tube preamps. Here is very dangerous high voltage and selection of components is very important. Are you already made something with tubes? No, but my friend can, he made a lot of preamp for sale. He will do it, but i ...

#34/#36/#39 scheme

Can you tell me, is this scheme right for making preamp or not?
Maybe there is some fresh scheme? Who was trying this?
