U373a

can someone please list the correct pinout for U373a compressors?

my schem so far looks like:

31= +24v
7/8/21/29 = -24v ... am i supposed to pin all those to my -24v power?
30 = Geh (ground?)

or is 30 for my -24v and 7/8/21/29 are ground? and then as far as inputs and outputs im totally lost

grazie

The important points are a little blurred...you are right about 31 for +24

7 8 21 29 are 0 V

30 (Geh for Gehäuse) is chassis ground


Inputs are to the left of the leftmost transformer 1 2 (a b) , outputs on the right 19 20 (a b)

no, one goes to the PS 0V , the others are for audio shield...

You dont connect -24V IIRC....that would give you 48V!
