Disconnected preamp and all peripherals so it is just amp and speakers and still get the tweet and hum when I turn amp on. No dimmers anywhere nearby. Are capacitors in a Krell 700cx hard to replace or can you use generic? Don't know much about them
Have a Krell 700cx and 801 Nautilus B&Ws using Krell Home Theatre preamp. Everything in system unchanged for 15 years. Suddenly now when I turn on amp I get bird tweeting sound from both speakers followed by hum. Checked speakers through other amp and fine. Know outlet is dedicated line meeting...
