I have burned up three amps (Sony STRDE845, HK 330, Sherwood 756) trying to run a surround system with 4 ohm Tower Phase Technology PC 500s as front speakers (Ebay deal). My next try will be a Marantz 7400 ($700 limit)). Does anybody out there have a better idea please
Yes. Get a separate power amp which can handle 4ohm loads. No cheap receiver is really designed for that so you'll might have problems with the Marantz also.

Jose, you probably have a short in the speaker somewhere: Burned voice coil; wires touching, crossover malfunction, etc. The HK 330 will drive 2 ohms easily.
The protecting circuit only worked on the HK. The speakers always sound great and have their own sub amp power. They work fine for a couple of hours and then the main amp quits. Could they short in the coil or wherever only after they warm up? Is there any way I can check the speakers. Will the Marantz be better than the HK. Thanks for the reply!
NAD receivers will handle 4 ohms. But it sounds like your best bet is what landroval suggested. Get a seperate amp for your mains. Parasound can be had and others for good prices used on Audiogon.
Guys I am not that knowledgeable about audio. I just found out the speakers ran fine on a NAD C350. Cant find one on the web. Could you please be more specific on the amps to get and I will act on it. Thanks again. JP
Ok, thanks to many of you I think I have it under control. I will purchase the NAM T753 for $800. So so price and out of my budget but the person selling it is also the PC500s repair rep and will fix them at cost for me if they are bad. Again I welcome any inputs today and Thank you all again!
