Brought in an entry level receiver that had the sound cutting out to Ametron Electronics in Los Angeles for repair. The service guy there walked me through what was happening and narrowed it down to two things; both of which would be about as expensive to fix as getting a brand new replacement of similar quality. They did all of this for free while I was there and saved me the hassle of trying to fix it when it wasn't worth it. Very honest and I would use them for any other electronic repairs I would need in the future. That rates five stars in my book!
