Model TR7

The TR7 was made from 1977 to 1984. It contained a single 10" speaker. It was a solid state amplifier, with a 7 Watts RMS rating, but it was designed with special "bounce-back" power supply, like a strobe, which made it sound more like a 25 watt amp. Features included tremolo and distortion circuits. Part of the TR Series, the TR7 was replaced by the R7 when the line was restyled. This is a great little home or backstage tune-up amplifier. For only 7 watts it clearly packs quite a punch. The amplifier shown in photographs here was purchased by Peter McCormack on April 15, 2000.
