Hello all...

I was all of bored and inspired by reports of these stereo receivers going
up in sparks and smoke from time to time to see what was inside this stereo
receiver and how well it was put together. I think they're actually a decent
piece of equipment as long as they're not abused or the specifications
violated. The following web page is the result:

This also applies to the Insignia NS-R2000 sold by Best Buy, possibly other
receivers produced by Sherwood with other names on them, and the RX-4105
model.

While not strictly related to the repair of electronics, maybe it would help
someone in such an effort. I'd greatly appreciate *constructive* comments,
suggestions and clarifications...especially for the section on the audio
amplifier, where I have only the most rudimentary understanding of what is
going on.

Does anyone have the Sherwood RX-4109 service manual kicking around? I'd
gladly pay for one and/or provide a valid e-mail address to which it could
be sent. (Sherwood hasn't responded to me in two days, and I have reason to
believe that none of the e-mail addresses on their site really work. I
haven't broken down and called them. Yet.)

Great write-up, William, thanks. For my sins, I play with earlier all-
analog stereo receivers (1970's and 1980's Sansui, Pioneer, etc.) I
can't seem to resists the low cost - even free sometimes! But they all
sound very good. Anyway, trying to give them up and stick to tubes!
If people want straight stereo from CD and FM radio, I recommend this
pure vintage route if you have the tech skills to check them out.
Cheers,
Roger
PS. I had a Sherwood S7100A in the 1970's - bought new!
