Maybe he ment to use them in an amplifer for switching AC such as filaments or B+ but was concerned about the effects RF may have on them..

These are usually designed to switch 60 Hz loads. They don't look like 
relays at RF. They generally have a fair amount of input/output 
capacitance.

I have a whole box of 'em too.
