"Marshall" sim

[tazwolf]

I am giving in to the temptation of building one of these - after I have tested it with two 9v
batteries which power supply should I use - a bipolar 9v or a bipolar 12v?

you could build a variable voltage power supply. thats my plan. im hoping it will act simular to a tube amp with a variac. right now im using two 9 volt batteries. i only built up to opamp 13(non-cab out)and it sounds friggin' awsome going into the clean channel of my valvestate halfstack(1960a cab).perfect joe walsh and evh tones.
before you build, i suggest using a stripboard?(the ones for wiring up ic's). i got all my stuff from radioshack- i used seven tl082's and had to use multiple caps in paralel to get certain values.---tom

Actually I've tried values from 9v -> 12v and I can say that there is not a big difference in sound as far as I can hear. If you go for 12v you may need to add another diode pair to GND. Go for a dual regulated psu.
