Yep, just read that in the service manual.

Going to work on a parts order list tomorrow.

Phase Linear released a service bulletin in like 1981 explaining what replacement output transistors to buy.  can't remember what they are, but they're a bitch to find, and they're quite often fake.

Order one extra transistor and give it the hammer test to verify that you didn't get fakes.
