NRG Control PA1 remote control

Otherwise, I would greatly appreciate, however unlikely, for some kind soul to lend me his NRG PA1 remote control so I could teach the Logitech.

Hey there,

it may be even more unlikely to be able to revive this 6 years old discussion, but I'll try to take my chance :-)

Since this weekend, I am also an owner of this incredible NRG PA-1 preamp (serial # 013). What a machine! It's so packed with relays, I haven't even started to count all those that are buried inside!

The downside is that the remote board simply seems to be missing. There are some dead wires that have more or less professionally been put aside. But worst of all, the rec out misses one channel regardless the selected source, and if rec out and the input selector are put on the same source, that channel is also missing at the regular output.

To find the cause and to repair this amp, a service manual or at least the schematics are certainly indispensable. Now that at least within this discussion we are three people who own or know about this preamp, does someone of you happen to have those documents or know where I could possibly find them?

Thanks for any help and hints!Thomas

OH! Thanks a lot!

I had seen the offer but never the photos—now I know that's because I wasn't yet registered here.

These schematics are a good step forward, thanks imhififan and pt1dyno.

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!
