I see these have been off the radar for awhile. I'm about to dive into a SA I have that has been out of action for too long. The last round a few years ago found some of the gold plated small transistor legs broke down. And had under the gold plating literally turned to dust. Causing them easily rip loose. Since then I have acquired a PSA parts unit so I'm headed back in. I've already worked thru the output modules and they are now up to spec. So the only known issue is the main motherboard which is the location of these transistors. This doesn't seem to be an issue with them all. So perhaps it's due to some past environmental exposure.
Nevertheless any recent service advice would be appreciated.
Many thanks in advance,
