One of my orion II's recently dropped to about 35 watts on all bands. I did
master reset. Took it apart cleaned front connectors and cleaned alc,pwr
and ref pots. I did notice that one side of the heat sink on the finals is
hotter than the other while transmitting into dummy load. Makes me think I
dropped one of the final transistors.

I have not found a schematic so I'm not sure what kind and how many
transistors are in the finals.

I contacted Tentec service via email have not heard back from them.

If I don't hear back will get out my golden screw driver.

Do you guys think I dropped a final. If so what kind are they and how many?
