NPN not FETQ1201,1204 are 34-1030 fets how do you test those with a DMM ?
Check this out first before you entertain my ideas.Your C2611's are not installed correctly. The pin out is the same as the originals. After removal check them with a tester, they may have been damaged.

They checked out fine still. So how are we suppose to install these? Do I need to flip them?Thought this is how the originals were mounted?Your C2611's are not installed correctly. The pin out is the same as the originals. After removal check them with a tester, they may have been damaged.
I'm guessing those two black dots near the center of the board are Q1201 and Q1204. Aren't there visible legs coming out of those which attach them to the board?Q1201,1204 are 34-1030 fets how do you test those with a DMM ?
So C2611 should look like this?More info to back it up

Pinout confirmed, ECB.
Just check for continuity between the metal plate and the collector pin. No continuity means they are not attached, so an insulator would not be needed. However, the metal plate is also there to better dissipate heat from the transistor to the heat sink, so it should be facing the heat sink.i guess some have a case collector and some don't- guessing these aren't hitachi ones.
