The preamp relay that gets removed is the white "R50" relay alongside the plug-in relay.

Once it's removed, the hole pattern in the circuit board will look just like the photo above. The two holes in the circuit board nearest the plug-in relay get the jumper wire across them as seen above.

I'm incredibly close to just building a pc board that accepts a normal, easy-to-find DIP type relay and drops into the circuit board where the white R50 relay used to go.

Hard part at the moment is finding what they call a "nail-head" pin. This is what goes into my adapter board, to mate with the holes in the amplifier's pc board. Cheapest ones I found at Mouser are over a buck each. Putting eight of them into an adapter board is more than the entire cost of the rest of the thing. Gotta find a chinese source, looks like.
