Question Simple 6L6 PP Guitar Design Needed

Hi Guys,

Im Looking for a Simple Schematic,

I just acquired a few vintage parts in great working order I would Like to use in a simple 6L6 PP power amp for guitar use.

PT is rather heavy duty as it was used to run 7-12AX7s,28 12FQ8's and a 5U4 rect. So power should be in ample supply.
The OPT transformer was matched to this unit driven by 2 6L6GC's and output was into 2- 12" vintage instrument speakers.
All donors from a 1959 wurlitzer organ.
The speakers will of course not be re-used.

My current supply of tubes is fairly wide so im not limited to only 12AX7's as drivers, Though it would most likely add to simplicity.

I have several preamp designs that produce tonal qualities I prefer, But I am looking for a bit more power over the practice amps I have recently built.

I would prefer something that is in the KISS league (Keep It Simple Stupid) as I am not a newbie, but no expert either.
Gene

There are sevferal very similar old Fender amps that use a pair of 6L6 and a pretty simple front end:

Pro 5E5
Super 5D4 or 5E4
Bandmaster 5E7
Bassman 5F6

Each of these uses two or three 12AX7 or in some cases 12AY7.

In fact, if all you are using is the tranformers and parts, you can buy ready made chassis, drilled and labelled for the models I listed. Cabs too for that matter.

The 5E5 and similar numbers are specific versions fo these amps. LAter versions got more complex, like adding tremolo and/or reverb. SOme of these have two input channels, and one could be eliminated to make it even more simple. SO I recommend looking into those specific schematics first. The differences between the models is not spacious. FInd one of them and you get the idea.

You can also get a lot of helpful discussion about it over at www.ampage.org
