Hey everyone
Ive got a randall RG100G3 valve dynamic combo amp. The amp uses a single 12AT7 valve in the power amp, my problem is that the valve gets microphonic in a very short period. I have 2 questions, does anyone know the amount of volts that gets sent to the 12AT7 valve in these randall G3 amps (valve dynamic power amp) ? i would like to replace the the 12AT7 with a retrovalves solidstate valve from jet city amplification. Ive sent randall numerous emails but they never reply. My other question, would it be possible to modify the amp power amp so that i can get rid of the valve.
Any help/advice would be greatly appreciated.
Thanks
Andrei
