help please
 
I am trying to find a 10k gain potentiometer for a yamaha a100 amplifier .
Yamaha stopped stocking parts for that amp 10 years ago !
Its a 4 pin surface mounted pot that also has 2 solder on pins to hold it on the circuit board , plus a 1/4 knob shaft sticking out .
It is mounted on a circuit board with the shaft sticking staight out protruding through the amps face (under the meters) .
I appreciate any help , these are great amps !!

Hi there, could you post a picture of the pot in the amplifier?Unless you can remove it and take a picture of it alone, that would be better.

yamaha pot
 
my camera wont take a good picture that small , but I have one I drew on powerpoint .
basically its 1/2"x9/16" 1/4 tall (from the board) it has 2 legs that solder it on the board and a 1/4" knob shaft that extends out .
it has 4 wire solder on points .

i found a part like this recently in either mouser or digikey. i had to fix a friends roland drum machine that had a similar part. i searched for pc mount pot and found a few different choices.

I saw the digikey ones , they were 3 or 5 pin (on the electrical)
I dont know if the 5 pin will work mines 4), but cosmetically looks good .
I need to look at the mouser ones !
Thanks for looking !!!!!
