re: S-7100A revisions?

I have two of these. They are externally identical and the *are* both "A"s. But the circuitry differs. One has the driver transistors mounted on heatsinks and the other doesn't. One is transformer coupled on the output, I don't recall whether the other is or not (it's home, I'm not). At any rate, they are significantly different.

Can anyone account for this difference?

Is there another schematic?

The working one is a great little receiver BTW.

re: S-7100A revisions?

I was authorized service for Sherwood in the '70s, the A had output caps but no driver transformer
The original 7100 had the transformer

re: S-7100A revisions?

Interesting. I believe one of them is actually the S-7100 despite the "A" designation on the label.

re: S-7100

I have one I just acquired. I put it on the bench and it sounded so good I decided to research it some. I'm not surprised at my findings. It's definitely a keeper. It's in absolutely mint condition. I go way back in electronics. I got it at an estate sale. As soon as I saw the name I started looking at it. They apparently had no idea what it was. I picked it up for only a few dollars the last day by chance of the estate sale. I'm very appreciative of the manuals folks have posted here. Thanks!!!

re: S-7100A

A fine "tube like" sounding amplifier that easily handles a 4 ohm load.Fantastic tuner, were once sold as secondary units in Macintosh outlets. So you know they had a pretty good level of quality.

re: S-7100A

This is good to hear. I just picked up a sherwood s-7100A to power my new musichall Marimba speakers, rated at 6ohm nominal. The Marimbas recommend 20-75 watts power. So the s-7100A should do just fine.
