I believe that this is a 1974 model.
It blasts at least 150 watts per channel into 8 ohms.
Made in the U.S.A.
I'm loving it!
I use it with a Pioneer SPEC 1 Preamp and a pair of Pioneer HPM 100 speakers.
I just got it back from Bill AKA "Turntable Daddy". He did a recap on it.
If you're in the Charlotte NC area, he does great work.
