OUTPUT MODULE
The output module sub board varies according to the output module that it is fitted to. It may require 1,2 or 3 VCAs to be fitted
and there is no auxiliary enable switching.
The control voltage circuits are identical to those found on the input VCA sub board as are the VCA circuits. A mono module requires 1 VCA, a stereo module requires 2 VCAs and of course an LCR output module requires 3 VCAs to be fitted.

ADJUSTMENTS
The only adjustments that may be required are to trim the distortion of the VCAs.
Input module PR2
Output Module PR2, PR4, PR6
Sending a signal of 0VU 1kHz through the VCA with the gain at unity the distortion should be trimmed for a null.
