For most mixers I build I use ALPS K faders with T-bar fixings for the knobs. For the poor man's tube mixer I have been looking for cheaper alternatives and have settled on the Bourns PTF series because they are lower cost, have a good feel and a guaranteed 1 ohm or less off resistance. So I bought a few and some knobs to go with them. They do not have a T-bar with pips like the ALPS but instead they have a plain upright lever that the knob fits onto (I think this is called Type A).
The problem is, the fit of the knobs to the lever seems to be very variable. Most knobs slip on all to easily and to my view are rather sloppy (but they feel OK). Also, out of a batch of ten, three will not fit at all. I am reluctant to push them on with much force for fear of damaging the fader.
Is this normal with this type of lever knob combination or do I just need to buy better made knobs?
Cheers
