Need alps 8203Y pin diagram

[ichiban]

Hi,
I need a pin diagram for the ALPS 8203Y

it has two rows of four pins

I have it connected and it does vary the

volume but I get hum output in its

middle control range, near the ends,

hi & lo the hum stops? I must have the

loudness pin confused.

Thanks in advance

...I get hum output in its middle control range, near the ends, hi & lo the hum stops?....

That usually means the *wiper* wire goes past a hum source.

I grounded the case of the pot and the hum was gone.
Thanks for the reply.
