Here are some voltages from my prototype. My power transformer has the following specs:
Sec 1: 250 VAC, 0,1 A
Sec 2: 24 VAC, 0,5 A
Sec 3: 9 VAC, 2,5 A
B+ is 269 VDC
F+ is 6,3 VDC
Test points:
B= 248V
C= 250V
D= 212V
E= 213V
F= 3,81V
G= 1,15V
H= 1,15V
I= 250V
J= 250V
Measurement were done with DMM minus to star ground, 1mA meter (fsd) and output tx connected (mandatory). Use VR104 for D/ E and VR103 for G/H to get almost identical values. Measure and recalibrate a few times, since almost all values will change when trimming the pots and meter.
Final calibration will be done with a test tone. A detailed description will follow.
