A friend of mine gave me some time ago (ok a long time ago) a project chassis from a Tweedle Dee that was punched pretty much everywhere with a couple of old radio transformers (built somewhen in the 60s). SE EL84 OT and a non-CT power transformer.
I had a bunch of PCB noval sockets that I wrongly ordered, a wrongly punched Komet 60 power board and wrongly ordered blanket turret board - you get the point around the Wrong in the name. Why horse is a rather long story that I wouldn't bother you with.
That is the amp's description, bullet style:
- quite a bit of filtering at the beginning of the dropping string with a 100uF capacitor, the others are 22uF - experimented quite a bit with various combinations and values and these seem to produce the best sound (to me at least).
- Rocket pre with some adjustments (I have best intentions to draw a schematic- bear with me) and half of the PI
- SE EL84 power amp
- PI half stage is switchable
- switchable voicing of the tone stack
- switchable voltage divider at the power amp entrance (i.e. lowers the signal and amp's volume)
I like the sound best with EL84 biased pretty hot (i.e. 11.5-12W power dissipation) with 335V on the plates.
The power is about 3-4 Watts with 8 Ohm speaker load.
I am having the headshell and faceplate built so these will follow.
To me it sounds great, being or not in the Rocket ballpark

Fancy a tweak?

And some sounds. First takes improvisations as always

All guitar tracks are recorded with the amp. No pedals. Somewhat moded Fender Telecaster being used throughout:
