Default One off guitar amp 2

Ok, I have been woodsheding like some wiesel in the barnyard, and built me a new gitar amp. My buddy said "whay dont ya build me a quad EL84 amp". Well after the last build "one off guitar amp" I chose to take up the challange and this is the result. Pretty much standard stuff,.

It's Loud!. I measure 40 v ptp into 8 ohms. And hooked up to a marshal 4 X 10 cab it will drive you out of the room.

I have to thank the DIY audio community because when this came up I started prowling for EL 84 schematics, and low and behold there was and old schematic of a quad EL84 setup. Oh I think it was in a Hammond Organ or sum such. Well I just plane stole it, and this is the result. If you dime the trebble control and the volume at the same time it will osciallate at about 24 Khz.!!! I know, I know, that's not good., I can make it not do that, but I have to give up some gain. I chose to let it have the gain/touch sensitivity. So howl away! Just dont tell FCC. Ok this is between you and me dont post it on the interweb.

About 25W, which is what you'd expect from 4xEL84's.

Be plenty loud through a 4x10, particularly when over-driven.
