Doesn't Bourns sell pcb types?
I haven´t seen any Bourns PCB typos so far....at least not with common/standard solderlug spacing.
Neither www.tube-town.net (that´s where I bought/ordered almost all my parts AND tubes (=awesome service!!) and still do) nor Banzaimusic has Bourns PCB pots....
Nice thing with the above mentioned PDA241 series is the higher friction/torque, especially for amplifier or FX applications....aside from the superb quality.
I don´t know if Mouser has Bourns high-friction PCB-mount pots though....shipping costs (at least 30€ to my loc) are in no relation to what I occasionally need in terms of parts
Nevertheless, out of the experiences I made so far, we tend to try and save some cents on the wrong end. We spend enormous amounts of money on tubes and stuff (best example being =C= power tubes....) and live with absolute crappy wiring, cables, pots, resistors, caps,.... But these cent-parts do have a big impact on tone and and performance of our gear.
Just my 2 €-cents though....
Have a nice weekend y´all!!!
