I picked up a JBL Urei 6290 last week for a very cheap price. Its fairly tatty cosmetically but it is working , although I havn't given it a vigorous workout.
It certainly seems BUILT where it counts. I really hate those little nut/ slot screws that hold on the covers. Very nasty like you see on A/C units in the US. Rusty too.
Anyway question is what are the nasties to look out for. I got it about biasing and will do that and I have cleaned about half a pound of crud from the heatsink and surrounding areas. The fan even runs fairly quietly now the blades are balanced.
Any action likely required on the PSU caps ? Anything else that usually needs attention ?

TIA Mac
