Thank you for reaching out.

I have a few questions.

1. Does the relay also function as an amp startup relay ?
2. Do you have a parts list for digikey?, the mouser one has a few items that are no longer available.
The PL 3000 Pre-Amp, I've got it back from Rolland Barr, he gave it the complete rebuild, good as new total cost with shipping just under $1,000. I'm looking around for some cables to connect it to one of my PL 300 Amps and Klipsch Heresy I speakers. So, I have two complete functional PL systems with a third system almost repaired, have two boards to replace on PL 400 Series II then that will make three complete unit
Feel free to call me with any questions.
I've only been licensed a couple of years ,still a newbie to all this .
But I have learned a lot from others.

I've been very busy with work and it's been several years since I've unpacked my PL equipment since purchasing a house. Just purchased another PL-300 II to add to the collection. Need to go back into the PL 400 II to see why it's squealing, did an upgrade on main caps and after move it just sat there. An anyrate, will p ost pictures of PL equipment as I get it unpacked and setup. CHEERS!
You got lucky with the open 2.7k resistors. When they fail the amp usually dumps DC into the speakers. Also the feedback cap and several of the display caps are failure prone.

I've got a drop in relay board to protect speakers against amplifier failure. It bolts on to the binding post so no drilling required. You can see more details on EBAY. Don't buy it there. I have to add in the various EBAY fees.
referencing the failed 700B power switch, I've got a stash of the Arrow Hart if you need one. Also you could drop in the triac board I've got. You tested it a couple years ago.
