I'm using them because it has two VCO's and it's more critical to have fine adjustments but I have also found it can be hard to get an exact setting with the single turn trimmers in the stock x0xb0x (or TB-303 for that matter). The part is also a standard drop-in replacement. They're not cheap but well worth it....
Digikey Part #'s
Mouser Part #'s
(they're significantly cheaper at Digikey)
They are not half expensive :shock:
These 12 turn fit and are a LOT cheaper
for the 5k81-PV37W202C01B00
for the 2k81-PV37W503C01B00
for the 500k
I included the trim for the 5.333v because its just as important.
Its just not worth using the single turns.
