There is more to the power ON/ OFF than the power switch and the relay.   I suggest you study the schematic before replacing parts.   It is more likely NOT the switch or the relay.    I'd more suspect Q1, 2N4124 or Q2, 2N4124.

That should be T90 relay, which is a 30-amp relay.

I have a Jupiter with malfunctioning main power switching. I suspect a sticking 
relay. The main power switch always turns radio on, but often won’t turn it off. It 
may take several times flipping switch to off position to get it to turn off.
Does anybody have the relay part number? The manual only indicates a Potter and 
Brumfield T30 relay.
Is it better to replace relay or can it be cleaned?
