Technics SA-300 that was putting out 40 volts on each channel. Does that mean that the STK packs (STK0039) are likely to both be bad?
I don't completely subscribe to the counterfeit rumors. Many parts of the world retain their equipment and repair it when it fails. There is a demand for good repair parts to keep the non-disposable part of the world running. Equipment is expensive in third world country's, so repairing the stuff we deem junk they make profit in. The STK's we see here are made for that demand. The main things to watch out for in repairing the module driven sets is find a seller with history in selling the modules. Second make sure the amps driver stages are solid and fault free before installing any STK device. Third, prepare the module and heatsink for mounting by trimming back the plastic edge of the module allowing the metal back of the module to meet with the heatsink (This is Key) as any output transistor would. The modules get HOT! even when running at low/min volume. It is imperative to have good thermal contact to the heatsink. I've repaired many module driven sets and have only success with all of them. A few had driver stage issues that needed to be corrected others just modules. The counterfeit rap - I believe, comes from novice repairs.
I haven't but I am gonna check it outAnd has anyone bought STK packs from this seller?

I was looking for something better than the STK0039 knockoff modules in my SX-680 and saw these on ebay. The sound is so much better now! The 680 has been running for over 72 hours and the heat sink is just warm to the touch.
I am about to get a pair of themPost 571 (http://audiokarma.org/forums/index....lacement-for-sx-780-and-others.721181/page-29) reports good results replacing STK-0039 with custom module in an SX-680.

I meant I was gonna get a pair and build them..lol..but how come no one is building them and selling them assembledThat was my understanding too. However, Dwayne Heath wrote he "was about to get them" not "make them" which is what had me wondering.
most likely the costs involved and resale value .I meant I was gonna get a pair and build them..lol..but how come no one is building them and selling them assembled
