Service for a Cello Performance amplifier?

Good day!

I have had your site recommended to me by a friend, I am hoping for a bit of reliable advice.

I have Cello Performance amps which I used in bridged mode, and which sat unused for a couple of years. When I turned them on recently, I find that one unit has evidently developed a short of some sort, the breaker clicked it off a few seconds after power-up.

I would Love to have this fixed somewhere close to home, these are a bear to pack and schlepp around. I am in central Ohio, can anybody recommend a reliable and capable servicer?

Thanks in advance, and very much!
