The missing rec out channel has come back to life. I'm pretty sure that after all these years sitting inactively on the shelf, the preamp needed to spend some time plugged in and switched on. One of the relays must have been stuck. The good thing is: They are either (triggered) on or off, nothing in between, so now that it's back, there can't be issues about dirty contacts or the like. But the preamp will need a thorough recap, I suppose.
Regarding the remote control issue, I'm also interested a lot which codes are used or how else this feature can be brought back to life.
Thanks again for any hints!
