A blast from the past, Peavey Profex

len62

I'm trying to resurrect my long dead Peavey Profex. I'm sure there will be multiple issues to address but my first order of business is replacing the data switch.

One of the wafers on the data switch has broken so I am looking for info on the data switch. The data switch is one of these multi wafer rotary switches that spins indefinitely in either direction allowing parameter adjustment.   I have contacted Peavey but no reply so far and had a trawl of the Peavey forum without any joy.

I'm looking for info to identify the type of switch so I can try and source a replacement, Anyone got any info or ideas?

Can you up load a photo of the offending item? The guts of the  switch that is

Not till Friday as it is in my mother's attic. But will do as soon as possible.

I did this with my old Yamaha A3000.

It was a mechanical encoder potentiometer but i cannot remember the model no etc.

I got the model number etc from the side/underside of the unit and checked here. They have a few different types so you may have to dig to get an equivalent part.

IIRC mine was an Alps unit which seem to be used a lot for these types of data encoders etc.

Hope that helps.

Thanks, I will start rummaging through those links once I remove the switch.

The switch/encoder is gone. I must have removed it back when it got broken. Surprisingly the Profex still works after around 8 years in an attic, I just can't edit anything.
