Can someone recommend a source for a replacement power switch?

It is a toggle type snap switch for an Optonica SM-1515B stereo amp. Hole
spacing is 1-3/8 inch. 120V.

You'll be lucky to find one of those without having to buy a thousand or so on
special order I reckon.

I am curious -- What's wrong with the switch?

It's such a simple component. Are the internal contacts burned or
worn?

Most likely. As the contacts are not replaceable you need to find an
exact replacement and there lies the trouble.

Need it be and 'exact' replacement? Maybe it's time for a bit of
creativity and improvisation?

Would any SPST switch with an adequate voltage/current rating suffice
(presuming it fits where the old one did)?

Looks to me like a fairly generic paddle switch.

It was probably marketed under the brand name "Panasonic". It may be a stock
design.

If you're looking for an exact replacement, here are some places to look:

(1) Authorized parts sellers for the brand of equipment you are trying to
repair.

(2) Distributors for the brand of part, in this case Panasonic.

If you're looking for an near replacement, here are some places to look:

(1) Electronic parts catalogs for places like Newark, Digi-Key, and Mouser.

(2) Surplus and remainering houses like Jameco, All Electronics and Parts
Express.

You are looking for a part with the same number or more contacts, with
contacts rated at the same or more amps and volts, and one that is the same
size or smaller. Mounting centers should match or be smaller.

Your replacement strategy may include fabricating a sheet metal bracket that
bridges any possible gaps.

Aside from the detail of fitting in the same hole, absolutely yes. Do
ensure you get a type suitable for *mains* switching.

Another viewpoint: Just permanently connect the wires (and apply proper
insulation), and switch the amp on and off with a correctly rated switch in
the mains lead.
Or, maybe even better, leave the amp powered-on.

The hole of the original switch can be filled either with the now
non-functional switch, or a nice power-on indicator. Add some creativity
here ;-)

That's ghetto, much better to fix it right, you might be able to disassemble
the switch and repair the contacts.

Why would it be better to leave the amp on all the time wasting energy? That
stuff isn't free.

I appreciate the comments and suggestions.

The switch that needs replacement is actually fine electronically. In fact
it is always on. The problem is with the snap action mechanism. The switch
lever took a blow to the side and broke some key plastic rocker parts that
allow the snap action to function. Any SPST switch rated at 120V, 1 amp?
will work but my preference is to maintain the cosmetics. Switch should be
OFF in the down position and ON in the horizontal. I thought this flat lever
switch was fairly common but perhaps I was mistaken.

I viewed some of the recommended sites but came up negative.

Just a WAG but have you looked at the voltage change switch from an old
computer PSU ?
