If I remember it properly, the SC504 has a very odd switching mechanism, not really fingers but a conductive elastomer.? The scope was originally spec'd to go to 100 MHz, but the contacts limited the bandwidth.? It's a rather fragile and picky switch, and I remember reading that it had very special cleaning instructions (if at all).

I need to write this stuff down when see it.
The comnent that I read was probably on one of the TekScopes, TekScopes2 or
tek500 forums.

Interesting, I wonder why that is? Obviously contact cleaner wouldn't be a
great idea for these type of contacts but I'm curious why paper wouldn't be
recommended. Too abrasive?

I can't answer that question (I'm sure others can), but ISTR that the

cleaning method should not be used on some TM-5xx(x) plug-ins.
