Title: Which card is which???
Post by: jwhmca on August 26, 2020, 05:28:24 AM

Pulled out the two 3-pack stand switch cards to replace the switches, pulled the caps off and now I can't remember which is which? The only difference between the EQ switch card and the DYN switch card is two tiny drilled out holes on the PCB. Which is which? drilled out is EQ or DYN???

**SOLVED**

The EQ card has two spots marked "E" that are drilled our. The dynamics card has two spots that are marked "D".

Would you have a schematic for these switches?
I have an E series schematic which advises to cut one trace for EQ cards only - coming off the +20v pin 13 line.
The G series schematic I have, is the one which has the 4 pin molex on the card.
There must be another.

I’m in a world of hurt trying to work this out. If you get it wrong, it shorts the +20v rail and blows your module fuse.

It says drill (cut) E1 E2 for EQ card, and D1 D2 for Dynamics.

Thanks so much! That’s going to fix the issue.
