Hello, my name is Wade Stewart. I am the engineer that designed and manufactured all Soundstream amplifiers and crossovers from 1981 through 1997. all REFERENCE and CLASS A’S. I am semi-retired now and am intrested in repairing all 'old skool' products. I will answer any questions you might have about those products, like I saw a posting where the gentleman wanted to know if there was any real difference between the REF500S and the REF700S. Yes, the 500s had 5 pairs of transistors per channel and the 700s had 7 pairs of transistors per channel. Like I was saying if you have any Soundstream amps you want fixed just contact me. I have 3 flat rates depending on the Power of the model.
