My 857D's main tuning knob fell off the shaft.? Looks like the set screw loosened just enough for it to slide off.? Anyone know the set screw size and tool size to tighten it?? My smallest metric bike hex wrench appears to be slightly too large.
(didn't? find the answer in the archives.? The rotary encoder and shaft are fine, just the set screw and knob are loose)
Thanks & 73 Steve KS1G
