Hey!
I got a Gameboy Advance unit (the first wide version), that has a broken volumepot.. (thumbwheel)

Its an Alps 303B pot (30kOhm).

Anyone knows where to get a replacement? On ebay and aliexpress they sell 10kOhm pots as replacements and claim them being original to the first version but they clearly are not.. (but might work fine anyway?)

Thanks in advance*!

I know this doesn't answer your question, but from experience with my original GBA ... I found the volume control on that trimpot was almost useless. I wonder if it's linear taper rather than audio taper or something.

It's a regular linear pot. Should I use a logarithmic instead you mean?

In 90% of electronic devices outputing audio they have this problem of providing linear adjustement for volume which leads for extreme imprecision in the lower part of the range.
