Hey Loudthud, Thank you very much!! I appreciate this, as I was not able to download other members who had this posted, I was able to copy yours. I have just struck a goldmine with some 12AX7's that are Vintage RCA's from the 50's. If you talk with WillH here on this site, He is the engineer who designed this amp, and he told me you could put either 6L6's in there, or if you prefer, EL34's like in the Marshall amps...I have not recieved mine yet, as I had to send a money order, it will take a little longer, but I am STOKED!! How do you like this amp Loudthud, now that you have had it awhile?? WillH says he designed this amp to have both the tone of Fender Twin, and Marshall amp, if you have the footswitch, you can play them seperately, or both together. That in itself is cool.
