I'm working on a Model 240 that has in interesting problem. After it warms up (an hour) the left channel cuts out occasionally, with static. It sounds similar to poor FM reception.
I have the service bulletins and I know that I need to have beta matched transistors in several spots. But before I go too far on a wild goose chase I thought I'd see if anyone has a suggestion.
