Default Sherwood RX-5502 Receiver Protection Shutdown, Repair, thoughts wanted...

Hi!

Why would you care so much about some Korean POS?


Well, because I can? Because I like 'em? Because the internal design
is pretty clean and straightforward? Because I like their sound and
think they're a pretty damn good modern receiver? Maybe because it's
just one other thing that won't end up in the landfill? Has the
purpose of this group changed since I was last here?


Your purpose in coming here seemed quite quixotic, not to say
masochistic, and therefore provoked curiosity:

"Suffice it to say that I've wanted to get my hands on a failed
Sherwood RX-4105 or RX-4109 stereo receiver to see just what it is
that kills them...abuse, misuse, weak parts, bad engineering/quality
control or something else. "

Hard to imagine anything other than frequent failure would provoke
this quest. A likely parallel in the automotive world would be a
mission to isolate failure modes of the Yugo.

Regarding the purpose of the group: Generally people come here to get
information to help them repair various pieces of electronic
equipment, often because their livelihood depends on it. Instead, you
want advice so you can redesign this run of the mill receiver for
greater reliability.


That's not the question I asked, or the information I wanted. Pulling
out my IR thermometer reveals that the regulator really isn't getting
as hot as I thought it was...about 124F or so at its hottest point.
I'll not worry about it further, though I probably will add a fan
powered by the lesser loaded regulator.


Why clutter up such a clean and straightforward internal design with
adequate cooling?
