If your integrated power supply makes an audible noise when like a big hungry bee, especially when the output power is at a value from medium to maximum.

When you switch off the radio, the power supply sounds like a "zip, zip, zip"...

If so, please check the coil L2 on the primary side of it.
L2 should have a DC resistance of about 27 ohms. If not, the wire inside is broken and the power supply isn't working correctly.

Be shure that you have unplugged your radio from mains before dismantling!!! High voltage on the primary side of the power supply, be careful!!! When the supply is open, check the capacitors also like described in other modifications.

    ...ebay. I will also file a case/complaint with my local sheriff's dept tomorrow. I'm good friends with the sheriff so I hope you'll be able to help me in this process. This guy has been a criminal (at least on eBay) for over11 years. I see the first post on here regarding his criminal behavior was in 2011. Has anybody else filed a complaint against this low-life scam artist? Any suggestions/help on getting my $$$ back would be greatly appreciated. Thanks!

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.
  • @ Toll_Free:
    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.
