Andy,
Here are the readings for T3
With Freq set to 0 the left Base (pin1) reads at approx +4.95v
With Freq set to 10 the left Base (pin1) reads at approx +4.95v (ie.. no change)
With VR5 fully counter clockwise the Emmitter (pin3) is reading at a slightly higher voltage then the base I would say approx +5.2v
And I get the same exact reading when I rotate VR5 fully clockwise.
I did do a reading on pin 16 of IC21 and I am getting -15v
