RE: Troubleshooting a JE Labs 300b amp

Did this occur all at once, quickly, or gradually? Have you checked the tubes? Easy enough to switch he tube from one am to the other, one at a time, to see if the problem remains with the amp, or switches to the other. Any other symptoms, buzzing, humming, crackling?
