    Output transistor for Sylvania CR2742 Motorola 526 002-3 ?

    Thanks in advance for any help anyone can provide. I am working on a Sylvania CR2742 Receiver and have a couple burned up NPN power output transistors. I don't have the manual for this unit but I do have it for the CR2743. This is the 25WPC little brother to the 50WPC CR2743. The output...

    Anyone Know Anything About Sylvania Speakers?

    Sylvania RS 5742 and T 5707 turntable combo

    Good day all. Does anyone know anything about this receiver and TT combo? All I found was the receiver was made in 75 and rated at 20WPC. I was curious about the sound and it’s place among the home stereos of the era. Any info would be appreciated.

    Sylvania self-service tube tester find

    Stumbled across this at Brimfield (weeklong, massive flea market in central Massachusetts). Brimfield has gone way up in price over the past 5+ years, so when I spotted it, I assumed the guy wanted way too much for it. Turns out he wanted a fairly reasonable amount for it and after thinking...
