First idea......

Try a sturdy needle-nose pliers. Stick the tips in the corner of the "nuts"
and pull apart ( open ) as you turn them.
However- I've seen old sets similar to this where those nut plates have some
hide glue holding them to the cloth.

Or- take a cheap Taiwan nut-driver and form a hex on the outside with a
grinder or belt sander. Wouldn't have to be a precise job.


Those pots wouldn't turn from the inside ?........

Need help getting off this strange "inverted-hex-hut" fastener:

How do I get this late 1960's portable suitcase-type record player
amplifier
out of the case chassis?

It seems really dumb that I've already put in serious time and re-built
the
record changer which now works smoothly, and seems like only problem with
the amp is 60-cycle hum from bad filter caps, but am getting stuck by the
fasteners holding the amp in the case...

It is held in by two strange fasteners "inverted nuts" which I've never
seen - the late 60's - early 70's seemed to be "the era of bizarre
non-standard fasteners". this is a family friend's childhood record
player,
so I really want to get it fixed even though it's not really collectable:

It seems I need a "reverse hex socket"; alsmost like a really large allen
wrench that's hollow in the center to allow for the pot posts. But I don't
know if there is such a thing, since I haven't noticed them at Lowe's or
SEars, and don't know how much it would cost to buy such a specialty tool.

Have you run into these connectors before? If so, how did you get them
off?
Are these in fact standard fasteners, that I might get tools for at Sears
or
Lowes? If not, what would be your first idea of how to get them off (that
doesn't involve a hacksaw or carbide drill bit?

I was thinking of trying to pry up two sides of the flat washer-shaped
parts
on the front of the case against the black speaker cloth, and then just
grasping them with a wrench to twist them off; then when I fix the amp and
put them back on, to try and flatten them back out again so I can push
back
on the tone & volume knobs.

But that could get ugly or break stuff so I thought I'd see if anyone has
other simpler ideas before I proceed. I usually don't work on these later
60's turntables, so would rather not shell out big $ for a specialty tool
off the web, but if that's the only way...

Thanks in advance,
