Re: Non-working attenuator

I test at the output of the IC35, I've got the counting as at the panel board.
I check the voltage at the output, and I've got a variation from 3.6mV (0 binary) to 15.6mV (10 binary). I think it's to few.
So, I'll check the KLM-368 board.
Howether, what is the signal "VCA Mod" for ? Because, when I check the "P.Vol" signal on KLM 368 board, this one goes on a 2SA798 which is a kind of double transistor, where the signal comes too, through an inverting amplifier.
I expected either the LM13600 or the 2SA798.
I keep you in touch
