Would someone please let me know if a TKD 2p65cs 100k ohm stepped attenuator would work reasonably well in a Threshold sl10 mated to a Threshold s/500 optical bias amplifier? The s/500 input impedance is 75k ohm; the sl10 was originally fitted with a 22k ohm Nobles pot gauging from the schematics. This sl10 was later updated with a relatively cheap 20k ohm dact-type generic stepped attenuator and it has an incessant problem with static and the mechanical steps are less than stellar in mechanical and sonic precision.
Alternatively, is there an alternative attenuator suiting an sl10, other than the relatively less costly ALPS-type or dact-type, that would work well?
Thanks for your help and information.

that one will work as charm, though - with nowadays sources, better to use somewhat lower value - 25K being all-rounder
if your sources are having proper low Rout (less than 300R), 10K is even better
can't really help with info about cheap attenuators, except mentioning DACT, which you don't like
now - worth checking that you don't have more than few mV of DC coming to CW lug of your volume pot; if there is DC higher than that, no pot is good enough - all will scrub and click after some time
in that case, your SL10 line stage needs re-haul
