Does anyone know of the value / a replacement part number for the gameboy volume potentiometer. The part is easily desoldered. I figure there has to be a new replacement - i'm just being lazy
anyone know - so i dont have to get my multimeter out
the original pot that is in it reads 303b or just 303 but, i don't know what that means!

303 would be 30, with 3 zeros. 30k pot.
although it may be a part #, not a value marking. a coincidence, its probably 30k if its marked 303. 303b would indicate it as a linear pot (i think).
right anyone else???
(this may be marked on the schematic as well)
30k on the schematic. I guess I should search 30k stereo pcb mount potentiometer... not showing much results. : /
You're probably going to have a hard time finding one that fits the form factor and pinout. It's just a simple voltage divider, so a wide range of values with the same form factor would work.
I'd probably recommend a transplant from a broken boy, or using this one for pre-pot (no-pot) prosound only.
do you think a pot from a gb color or pocket would work?
Even though B means that the Game Boy uses a linear part, I think that a log tapered would be better.
ok - I think I really found the part this time. this one is 50k not 30k, but I don't think it should matter. kitch - stock them?
obsolete part though 
maybe there is a replacement?

It seems like it's got the right height, but a 16 mm diameter seems a bit much. (Don't have an opened boy around so I can't check, but it looks like it's smaller than that from the outside.)

i think a 16mm silder would be awesome personally
ah - i screwed up - the pot is actually a 103
...stupidly, i was looking at the dimmer pot
at any rate - so i think the vol pot is a 10k micro potentiometer (which makes a lot more sense)
actually took nitro's advice and took one off of a shit blob top GB and transplanted it back onto my good one - only time will tell how long this one will last - workin good so far though...

i just did this to my dmg-cpu3 board. underneathe the pot, the board is labled "VRI, 10k x2"
i believe that means that theres 10 through 2 channels, yes?

probs just means its stereo ; ]
STEREO SOUND!
