Just picked up a 500 (paid way too much for it but, really, how many of them are there down here in NZ!). Anyway, started the teardown before taking these pics but all the knobs are present.
Right, to start, its working completely fine -- no noise on any of the pots or switches and less than 5mv of DC offset on both channels.
But that's not a reason to leave it alone, so it's "new thread" time to get some recommendations as to what to order for a restoration (gotta get a Digikey order in before Christmas [and it needs to exceed $125 for free shipping]). I've already got the main caps and relay on my list. Are there any semi-conductors that should be changed?
Probably won't have much time to devote to this one until I get the house to myself in a couple of weeks (for a month!!), but please send through those suggestions.
Cheers
