Need good audio tech in Seattle

I have a Carver "Receiver" that needs attention. No balance control or loudness function. It also seems to wimp-out when turned up past 1/3 and blows a fuse. Weird. Who can recommend a good tech in the Seattle area to fix it?

G'day Mate from New Zealand. Everett Audio in Everett WA bought all the schematics and tech stuff from Carver . They might be able to help. If that doesn't work try EBAY the auction site. I have purchased owners manuals and schematics reasonably there. Keep looking. Cheers, Rob
