I am currently waiting for my, all new, rework/soldering station to arrive and I will try to use it to change them myself... I know I might fail but I will give it a try... Anyway is there any way I can check the opamps to find out if I fried them already?

I am not able the fix that by myself. No wonder it didn´t sing. What can I do? Regards Peter Odense Denmark

I do get at severe background hum though. The GND lines are connected to true earth (a spear in my backyard) so I don´t get it. Any tips, tricks or ideas? The retros are powered by Placid Bipolar psus, also ground connected. Anybody?? Regards Peter Denmark
