Hello All, First 18 Watt TMB build and I have some questions about some voltages that don't seem in line. Let me say that the amp seems to be operating fine and sounds fantastic.
It is basically the Ceri@tone layout without the Diode setup on the Rectifier tube. Mojo trannies. Tubes are Electro Harmonix 6CA4, Ruby EL84CZ, Ruby 12AX7AC7 HG, Ruby 7025SS HG, and an EH12AX7 PI.
I installed a Tube/SS rectifier setup with a switch. IN4007 off of pins 1 and 7 V6 to Pin 6 to one side of switch, and a wire from pin 3 to switch. Voltages are-
V6- Pin 1-7= 301v Pin 3= 370v, 392v SS
V4 and V5- Pin 3=8.2v, 9.2 SS Pin 7= 247v, 262v SS Pin 9= 257v, 272v SS
Curious as to why V6 pin 3 seems high, and V4-V5 voltages seem low. I didn't check V1-V3 since I did the rec mod. Thoughts?
Thanks in advance!
Mike
