Dodgy speaker relay fixes?

[Brian Gaff]

I seem to have an issue with some Denon amplification gear circa 1990s. Its
got a relay which delays the speaker connection till the voltages have
stabilised, but the contacts seem to get dirty every few months. I assume
there is not much one can do except attempt to find out what sort of relay
it is and fit a new one. All I've had done so far is just run a thin piece
of paper between the contacts, but wondered if there was something which
might last or perhaps the actual sprinyness in the relay is now crap.

Well,that won't do much. They used to make relay files, but you can go
after it with some wet or dry sandpaper. 600 or finer (step it coarser
to finer if you have several grades, very fine grades you get from auto
paint supply stores). Cut out a strip, fold it half so both sides are
abrasive, then run it through the contacts while holding the relay
closed. If they are just oxidized, some contact cleaner will work.

Perhaps you don't even need the relay if the pop doesn't bother you.
