Hi..
I installed only the driver 2166 which is new, and tested current on the test points..it goes from 0.30 to 1.3 and I stopped there, was getting to hot...all trimpots are adjusted accordingly by the service manual..any suggestions?

could be..although it was bought from a shop, not online..
In case I get a genuine, and it happens again, what should be checked? there was a bit burned 100 ohm bias resistor, and I replaced it for a new one

I have a TRC 449 that has the same test points bridge..thinking about comparing current idle and activity at the test points, to see if both act similar
