Sduck is correct, the 148/149 refer to the elements.
The only log pots I ever used on MOTM of 148/149 type are on the audio input
attenuators (like on '420, '440, 480 and the '830).

Not quite - 148's are plastic conductive elements, 149's are Cermet
elements. Either can be linear or audio. And I'm not so sure they're
supposed to be audio taper - I'm pretty sure they're linear, but would
rather hear a definitive answer from Mr. Paul S.

some confusion over the way that the Spectrol 148 100K pots are listed
differently between the motm 190, 390 and 480 parts list. The 390 and 480
lists both specify the pots to be logarithmic, while the parts list for the
motm 190 only lists "3ea 100K cond. plastic Spectrol 148". I purchased the
pots I thought I needed for the 190 on ebay, that were listed as Spectrol
148 LIN pots, not LOG. Can anyone clear up this confusion for me? Do I
need Spectrol 148 LOG pots for the motm 190? Any advice is appreciated.
