For your consideration, we have a rare Gala Sound Symphony 4 Belles Research Labs Amplifier. The amp was designed by James Gala, and Dave Belles in Rochester NY. It was manufactured by Dave Belles at Belles Research Corporation around 1995. This Mosfet amp is 200 watts per channel, has two large toroidal transformers, and 24 output transistors. The amp is in working order, and sounds very nice. The previous owner used the amp to drive a pair of Green Mountain Audio Continuum 1.5 speakers. I spoke with Dave Belles, he is still working, he remembered the amp, but did not have any information for it as paperwork got lost over the years. 

In order to test the output and check to see the amp was in proper working order, we hooked it up to our Sencore PA81 Stereo Stereo Power Amplifier Analyzer acting as a dummy load and Oscilloscope interface. Using an audio generator, we ran a 1k signal through the amps input, slowly increasing the amplitude while monitoring the output on our oscilloscope for signs of noise, clipping, distortion, or improper channel balance. It checked out perfectly, and  the amp easily produced a clean 200 watts per channel on our bench.  Following the work performed on the unit, it spent time on our bench, and then in our house system for about three days running daily for 8 hours a day. It performed flawlessly.

On the outside, the unit is physically in good condition. The wood side panels and the metal work have some scratches and blemishes, but the unit presents itself very well.  On the inside the unit is clean and there are no signs of bulging or leaking caps. There are also no signs of heat stress to any components. See attached pictures for further details on the physical condition of the amplifier.

We don't have the original box for this unit, but we take packaging and shipping seriously. We spare no expense, use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.
