Belles Research Corporation? ?

I believe they're still in business. Recall seeing a Sam Tellig review of one of their pieces a few years ago. Nice stuff for the money, as I recall. Audio Connection in Verona, NJ used to carry them, may still, you might want to give John Ruttan a call if you can't locate the manufacturer, he may be able to help.

www.powermodules.com is my guess

makes the best amps for the $ in the world.

HI, yes DAVE BELLES now goes by POWER MODULES.I had a belles 400 power amp.was a killer amp,retail was $1800 in 1989.he is still getting rave reviews.checkout www.soundstage.com for reviews.I have spoke to DAVE a few times and is always a pleasure to talk to.he is down to earth and will not rush you off the phone.RICH

Belles Research was the first, then OCM (Magnum Research I think) and now Power Modules. A friend has my old preamp from the original Belles and it still works great. All of his incarnations have good build quality and solid engineering. I had the 150A Power Modules amp for about a year and it was a nice unit. Did you listen to the amp? Bet it sounds pretty good.

The Belles I would be 1980's. Previous post are generally accurate. Also was a matching Belles I preamp superceded by the XLM. Came in silver or black. Amps had either rack-width panel with rocker switch or narrow panel with toggle switch. I have one of each and they are still fine amps. :)
