Hey Turbo- I dont know if you have fixed your 2230 yet, but I have quite a few parts/components and if there is some device you need that I might have, feel free to shoot me a message. I know the shipping and minimums can add up quickly when ordering, and I know I have stuff I will never use. I also have a complete NOS amplifier board and output transistors with heat sink that was intended for field warranty service on the 2230. That might be for sale, although it wouldn't be cheap, but it certainly would be one way to replace an entire channel, lol. Well anyway, let me know if I can help you out....you sort of get addicted to this stuff, lol.
