1970's Sears Combo SS Stereo

Hi everyone,
Another box unpacked for service.
I started looking around the cabinet to open it
up to remove the BSR changer.
I then noticed this gal was dropped on one corner,
and part of the heavy plastic and wood frame bent.
Once I got the frame off, I figured out I could glue
and clamp the damaged side.
After that, I found a steel L-frame piece that I was
able to bend, to provide a pull to make the frame
fit back more or less square.
Problem 1 solved.
Then I noticed the controls on the amp were
scratchy, and the spring button push On/Off
switch was sticking badly.
There are also a whole line of push button controls
under the pots, that were acting up badly.
The pots and the On/Off were finally cleaned up.
But, the lower line of push buttons were hidden
by several PC boards mounted on top of them.
I decided to just shoot the heck out of the
Nu-trol and CRC electrical cleaner and hope
it worked. It did.
I cleaned up and lubed the nicer BSR changer,
that has a magnetic ADC QLM MK III cart.
Replaced the stylus and adjusted tonearm
set-down.
I had a nice set of Realistic Minimus-4 speakers
that matched nicely.
The radio circuit is pretty nice and pulls in
weak stations.
The 8-track needs a belt, but I'm not going
to worry about that.
Ms. Sears is done, and sounds very good.
On to find a home for her.
