I'd like to fix my old receiver/amplifier. It has a broken button "balance", but after opening and extracting the component I have no idea what I should buy to replace it. From my point of view, it should be a potentiometer, but some people say that it is a rotary encoder.
In any case, there is no idea what to order; I googled the numbers, but I did not find anything that would match. Please see attached photos, which hopefully will help.
Following the advice of @Justme, I found: R393 Part No. 5104225 Description N11RGLC250KW22Z Variable, but again Googling does nothing, and searching Mouser for the part number gives "Thick film resistor".
I'm attaching a part of the schematics. It seems that it strongly resembles the Bourns PTT111 model, but Bourns does not produce 250k Ohm potentiometers. Only 200k and 500k. Is there anybody else who produces such a type of potentiometers?
It seems that the manufacturer is ALPS.
