Static from Speaker on Krell KAV 250 Power Amp
I noticed a static/distorted sound coming from my left speaker and thought the tubes on my ARC LS-15 were going. I bought new tubes from Upscale Audio but the static sound was still coming from the left speaker. I hooked up a different speaker and the static sound was still there. My guess there is a problem with the left speaker terminal on the Krell KAV 250. Anyone with similar problems? Suggested fix? Thanks.
