    Dynaco stereo 400 distorted channel repair

    Hello, left channel is distorted at any volume. Found the emitter resistors to be brittle and cracked. I have a mouser cart to be filled. Any other known 400 issues? For now I've ordered 2. New pc-28 boards but if I can fix with a few mouser parts, I'd save $170. Which I'd prefer. Thanks yall.
