I upgraded the power service into my house to a 200 amp service. Anyhow every system in the house gained both sound quality and a hum. I got rid of the old wore and went copper all the way. Had the electrician come again and had him check all his connections. He tighten the main ground. It was already tight but he made it tighter and the hum was gone from every system in the house. Above where the fellow says check the power cord that is free and only takes a few minutes if it is not the problem it was free and o ly took a couple of minutes. Sometimes things are that easy and that cheap.
Issue with Krell KSA-250
Hello-
It's been a minute since I've been on the forums here, but I'm glad they are still around!
I am the second owner of a Krell KSA-250 amplifier. For the past 10 years it hasn't given me any problems. Then today, when I turned it on, it emitted a rather loud buzzing sound. This wasn't coming from the speakers (like a ground loop hum), this was a very startling almost "mechanical" buzz sound. The buzz does not stop until I turn the unit off.
I'm not sure where to start. I called my local audio repair store, but they don't work on Krell. They suggested I contact Krell, which is my next step, but seeing as I'd have to freight this for it to be repaired, I'm hoping someone here might shed some light on what's happening. I've made a short 15-second video of the issue, but I don't think I can upload it here. I'm happy to provide it though.
Any thoughts you might have would be appreciated.
Thanks,
Blake

@jayctoy Jayctoy more good ideas eliminate the cheap easy things first. Sometimes it does get the problem but many times you can find an improvement non the less |
