Ok, this has me absolutely stumped. I've been through everything I think I can look at and then some.
Long story short...SI deluxe board...all sounds are fine and it seems to be working fine on the bench.
Take the boardset, I mean every board - mother, daughter, and power, into the house and plug the same exact boards into my cab. Missile sound doesn't work - its very brief and quiet, as in barely audible. All other sounds are fine.
Bring the boards back out to the bench...no problem - missile sound sounds fine and just as loud as all the others.
The bench rig is a real, cocktail wiring harness complete with real brick and real original analog power supply, even using a cocktail control panel. Only non-original parts the bench has is the monitor (a TV) and the speaker (using computer speaker).
The cab is an original upright, non-deluxe SI. As far as I've compared, the pinouts are identical, except the non-dlx cab is missing pins 12 and 13 off the larger plug that apparently go to the...monitor?? In addition, I believe the cab doesn't have a "monitor centering supply" that the bench transformer brick has.
What the hell is causing the missile sound to flake in the cab?!?!?!? I even tried clip leading on a different speaker...same thing.
