Several years ago this was a frequent issue with K2s. On some units the knobs were a very tight fit. My SN 1289 built in 2000 was one of those. I got the knobs on mine okay, but some people damaged their pots installing the knobs. Others resorted to sanding or filing the shafts to fit.
I don't recall what the "fix" was, but the problem seemed to go away.

The other potential thing could be a burr of some kind on the inside of the knob. Should you find one like that, I would suggest turning a twist drill inside the hole in the knob before attempting to attach it to the pot shaft. I do not know how to recover from your current situation without possibly damaging the pot. If I were doing it, I would order a new pot and after that attempt to remove the knob in any way that works (including destroying the old pot) - I might order a new knob too just in case I could get the old one off without damage 73, Don W3FPR > -----Original Message----- > > After a few hours of IARU cw contesting picked up the #3612 again.
