I am looking to find out anything I can about this amp. Trace Elliot GP11. ( Year made and discontinued, output, opinions, value, reliability...etc) It is solid state and has a fan inside and a handle on the right. A and B spkr outputs on the back; 4 ohms. No SN# or model # on the back or to faint to read. I have it on indefinate loan. It sounds real nice. Thanks for any input!
