Hello Everybody:
It is the LCRU that is bad. Connected the sound card directly to track power and it works great with both the Commodore and Hudson sound chips. When the sound card is plugged into the tether it does not work in either conventional or command. Placed a VOM on pins 1 and 2 (they supply the sound card power) from the engine and received a reading of about 12v in conventional. I suspect that the current output is the issue most likely caused by a failed card or an aged solder joint. I plan on re-soldering the wires to see if that fixes the issue.
Marty, can you please let me know how much you want for those parts, I like having spares and like you I share a great deal of "classic" parts with others. I am new to the forum and not really sure about the rules of discussing purchases and giving out email. As such could you please contact me via the tca-gulfcoastchapter.org website. Just go to the contact us button in the menu bar at the far right hand side. I check for emails from this site every morning.
I would like to thank everyone for their help. You helped me solve a perplexing situation.
