Suggestion??  Throw it all away and leave as is. Except for an unproven
potential problem with a 20-30yr old switch there is absolutely no reason
to use a step start in that amp...other than to increase the profits of
the seller.

I have a few hundred irreplaceable switches on hand when old age finally
catches up to them and a really enterprising ham cant figure out how to
repair the original.
