boon studio in potong pasir, near jackson kopitiam.
yes, davis sells pot. the last time i bought was abt $5 or 6$ if memory serves correctly. 500k, I think its gotch, made in japan, very good.
boon selling the same one also.
u can use those pots from Sim Lim tower but they're Linear pots not Logarithmic pots. I recommend Log pots instead if u're replacing ur volume pot. Linear pots are useless for volume unless u want a huge jump in volume as u roll up.
davies sells the pot. and well since u're changing. u might also want to consider getting a push pull pot? if u're good at circuitry anyway... to have more options on ur PU config.
