Does anyone bulletproof Rock-Ola Amplifiers?

[shawn1976]

I have a Rock-Ola 4000X Trilogy that is working but has a large amount of distortion when playing music and was wondering if there was someone here that would service the amp?
The amplifier is a 280 watt Rock-Ola 56180-A amplifier.
Anyone that can help me out with this please let me know.
Thanks.
