Information on a 1987 Sony 500 ES Spontaneous twin drive

popcycle

I bought this Integrated Stereo Amp from a Pawn Shop it was extra clean and everything works. It has the biggest transformer I have ever seen. I have four stereos, but this thing is a monster. I went to Sony to see if I could get some info, they said they were emailing me something. If anyone nows anything about the power output or anything else could you please drop me a line.
Thanks popcycle

P.S. I have a stereo with a 120 watts a channel and this Sony is atleast 3 times as heavy and the transformer is 4 times the size?

That's probably part of the famed TA-Fx00ES series of integrated amps. They are nice. I'm guessing your's is a step down from the TA-F700ES, which is talked about at The Vintageknob.org

My guess is it puts out a conservative, clean 80 watts/channel.

I had the TA-F333ESL, which was the same as the TA-F770ES, but international voltage. It was a very fine piece.
