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,

Take it from an old stereo collector. Get some Deoxit from www.partsexpress.com.
The switches including volume pots get dirty, corroded, etc. Squirt
some Deoxit in the switch with a paper towel underneath for drips.
Work the switch back and forth 10-20 times while unplugged. Give that
a try. I can't tell you how many vintage receivers that I picked up
for almost nothing at thrift stores that had problems with the pots
and switches. Deoxit works on many switch types even car window/door
lock switches that the dealer wants mega bucks to replace. Most of the
time the contacts are just dirty.
