Who can service Bedini amps?

It's not that exotic. I would trust it to any well-reputed tech near you.

You might try giving the Shahinian plant a call.For many years, they recommended Bedini amps to drive their unusual speakers. I believe Richard Shahinian was a friend of the Bedinis.

John Bedini’s has a company called Energenx. http://www.energenx.com
They are located in Idaho at 208 – 772 – 3303.
Bedini still fixes the amp you have.
Give him a call.

Thanks all. Doug, I've tried numerous times to contact john bedini including the number you provided. Never got a response. I've read some customers who sent him their amps for repair and never got them back or took years. I've decided to go with Jon Soderberg of Threshold fame.
