Yes, yes - Song-Huei have proved very good - decent quality and price,
great service (ask for Sandy and say I sent you)
I tried the SH R0904N [-B100K, L-20KQ is a typical type] as alternative
to the quite expensive Alpha 9mm snap pots from Mouser and have been
very happy with them.
Price on these (MOQ 1000) is $0.13 !! ie. a fraction of the price of the
Alphas via Mouser. Of course, price is nothing without quality - suffice
to say that quality has appeared to be top-notch.
I paint the slots myself (quick dab of paint on a piece of wire, then
wipe of excess with my finger - not as pro as Robin's method...! but
For my standard metal panel pots (vertical PCB mount) with spline shaft
I now use their R1212N (or R1214G) -
- note that these are available with optional upgrade LongLife element
for just a few cents more per pot.
Typical option for me: R1212N - B100K, L-15KC / M / 100k LL @ $0.27 each
- again, MOQ1000 - 100k LL at the end means the LongLife 100,000
