The tape is on the CPS A board JAMMA edge, not on the unifier edge.That seems wrong.
I can understand that the main board amp is powered off, it might cause unintended buzzing or feedback.
But if your Qsound board has no 12V power input as a result, it will never output mono amplified sound into the Jamma edge.
Did you meter the 12V area on the qsound board? Does it get +12V DC with the tape in place?
Edit: Technically you can do this as follows, but i'm at work, have no 1.5CPS with me, or at home, and no easy access.
- Remove the tape from the jamma unifier edge.
- Add the tape to the jamma edge on the CPS1 A board
That is where the tape is at the moment.
Oh I get what you mean - the 12V should be distributed from the JAMMA unifier to the Qsound board as well - I wonder why that's not happening.
