parts list

 (Note, this parts list reflects "version 2" of the amplifier, which doesn't actually exist yet: i.e., this is the newly-designed version using 4x12AX7 and a switching power supply, so no EZ81.  Schematic so far only reflects "version 1".)

schematics and layout diagrams

Image
I'm posting rough copies of the schematics again (just photos), including I think a few minor changes and corrections over the "nicer" copies posted a while ago.  Also, for the four pages comprising the preamp section, I have now made layout diagrams: i.e., slightly re-factored schematics which more clearly suggest how the circuit board and wiring will be laid out.

quick-start guide for the version-1 prototype

Image
McGrath Mini Quick Start Plug guitar cable and power cable into the back. Flip all the switches into the "on" or up positions, except for the fx switch: keep this one down. (back view) 5 switches on, 1 switch off ( fx ). Since this is a tube amp, you'll have to wait a bit for the tubes to warm up, before you can get any sound (around 15-30 seconds).  When the amp is warmed up, the power LED changes from red to purple. Start with all the knobs pointing straight up ("12-oclock position"), except vol : start with this at minimum (full CCW). (front view) Strum a chord on the guitar while gradually turning up vol  until the volume is good. The most important knobs other than vol , in setting the tone of the amp, are the two  gain  knobs.  Experiment with these.  More gain leads to "dirty" or distorted tones; reduce gain for "clean" tones. Dirty tone: Semi-clean tone: Experiment with the rest of the knobs, and with different settings for the switc...
