Thank you PRR and all the other guys for helping figure this one out. I wondered if it could be done and it indeed can be done. A 7 watt ( more or less) Liverpool. Its not exactly a liverpool but rather my interpretation of a liverpool ( i dont care for el84's). I followed and express schematic till right after the PI caps. from there its 2 6v6's (220k grid leaks) 400R cathode unbypassed 1k5 screen resistors, 4k7 grid stop resistors. 11k5 OT primary into 8 ohm speaker. Could have built a better power supply. 33uf>220ohm>33uf>1k5>22uf>1k5>22uf. Second to last node feed both PI and GS 3. Hope this helps anyone interested and thanks again for all the input from you all.

Sounds nice, congrats! Crazy graphics hiding the pseudo "f" holes and couldn't make out where the pickup switch is. I'd like to hear the high gain w/ a solid body too. What 8" speakers are ya runnin' down below?

Good Stuff. :icon_biggrin:

Thanks! The pickup switch is right by the volume knobs and is on the neck for clean and bridge for dirty most of the time. Graphics ala sharpie oil pen! I had to draw the skulls eating the f holes. Just seems natural. I want to back light the f holes with a led inside...another day. The 8" speakers are celestions out of a boogie amp. Vintage 8's of some sort. They were paired with a vintage 30 12 at one point. I tried a les paul with this amp and it sounded good but was a little bright. It was a real 59 ( so cool ) that my friend has with the original pick ups. Coincidentally he owns the amp now. Thanks for looking!
