I contacted Grant audio and they were of no help. Email to Sheng ya provided no response. It is a shame that there are no service centers that are set up to handle an amplifier that is sold world wide under several names.
Repair of a Sheng ya sp-991
One of my amps is not putting out any power. Took it to my tech and after 4 hours he gave up unable to work with a Chinese made shengya without the schematic. Love these amplifiers and do not want to replace them. Does anyone have any experience with the Sheng ya sp-991 repair. It is the monoblock that puts out 100 watts Class A and 300 watts total in A/B configuration. Some say it is identical to the Vincent sp-991 or the Kavent p-220. Live in the
seattle area.
