Question about Krell Audio Players & Recorders
I have a Krell FPB 300 amplifier use to power my martin logan SL3 speakers. When the amp is about 1.5 hours running you will hear noise coming from inside the amp sounds like a small motor( the amp has no fan) but when you stop playing music and idle it it will lower the sound and when you put music back it will be there again, and it does not affect the sound.But on the first hour there is no noise at all. Please give some advise.

Hi There WLAW,
I am in Auckland NZ and do repair work for a high quality Amplifier chain so I could have a look at yours for you....
Being Local in Auckland it will save you sending it away off shore to Australia.

If it has a voltage selector for 220v, once configured it will work just fine Being electronic instead of mechanical the power frequency won't affect it. If it doesn't have a voltage selctor, don't plug it into 220.
