Old Technics stereo receiver, circa 1988.

Power switch. Button in in - unit is powered. Button in out - unit is unpowered.

Now, if I just push the button to power it, it powers itself, then powers
down. If I push the button in and release it -very- slowly, it'll stay on.

Any feel for what I'd have to go thru to repair or replace the switch?
Unplugging the unit to put it on a workbench is only slightly less
unpleasant than an enema with a firehose. :-)

Thx,

If you can figure out how to open up case, you may be able to replace
switch provided you can find one which is compatible with space and
opening on chassis. You could always cobble together something which
would work.

Chances are it is only a matter of squirting some cleaning fluid into the
switch and working it a few times to free up years of accumulated gunk.

I would first purchase some electronics cleaner at an auto parts store or
Radio Shack. Open up chassis to access switch. Squirt the cleaner into
switch wherever I could. Work switch a few times with power off, of
course.

Plug in unit and see if it makes a difference.

This also works for scratchy volume controls.

If none of the above works, just leave the switch in the ON position
and use a power strip to shut it off. Thats the easiest solution, and
if the switch dies entirely, you can just solder the wires together
that go to the switch and continue to use the power strip.
