Hi all,
I have build one of these and I am not quite sure if it works right.
The gain potentiometer works but I am getting full amplification when
the pot is at half range, at the rest range there is no change in
sound.
Also a light 50hz hum is introduced while adjusting the gain control, is this normal ?
My unit is unmodified and does not have the output normalled to input 2.
What is your experience with the original CGS65 Tube VCA ?
Which modification would you recommend?
Thanks
