Michigannick …. The Toshiba's of that time were underrated but really strong. Toshiba parts were found in EVERYONE's gear back then and the Toshiba power transistors (red lettering on the TO3's) of that day were excellent. Toshiba was a tougher sell, because it was not as well known as Yamaha, Hafler, Pioneer, McIntosh and even Nikko. But, those who bought it were always very happy with it. I don't recall ever getting any Toshiba back for repair - now that I think about it.
I didn't know it back then, but that was the "golden years" of audio. I had a blast as I worked in the store about 25 hours a week, attended college (Baylor) full time and did some pro-sound gigs on weekends. I also did all of the "event" sound mixing at the university's largest auditorium. Used a lot of Crown, BGW, JBL, Altec, EV, Frazier, etc. back then. I remember the amp racks for PA systems used to weigh so much that it took 4 strong guys just to unload them off of the truck! Now we have high-tech power supplies and Class D amps that produce 4x the power at 1/4 the weight. Oh well!!!
