Hallo
I have a Proton AP 1000 preamp wich has a switch to bypass the tonecontroll circuit .
I dit a restoration caps, relay cleaned input switches and replaced the switches at the front for mono bypass etc anyway .
The tonecontroll switch when pushed makes a popping noise, it did it also before the replacement of switches the switch is a shorting type .
The noise is normaly not that loud sometimes it is very loud .
I don‘t like that
some help to determine the problem would be great
best
