Hi Patrick, Indeed there was a third felt washer with mine too. Presently I do have it installed with the 2nd one in place. My knob wasn't loose though, it was quite firmly attached once tightened. When I first felt the knob rotate properly for say, 200 degrees of rotation & then bind a little for the remaining 160 degrees (making up numbers here but fairly accurate), I removed the knob and saw a little circular scratch on the clear plastic cover where the edge of the knob had scored it. I then put the knob back in place & put the K3 on end & looked from underneath along the front plane & saw the knob was resting with a slight tilt. Again though, this knob wasn't loose, it was firmly attached.
I removed the knob & put the 2nd felt washer on top of the first to get it off the plastic and add some tension and then tried it again but when rotating the knob, I could hear a felt on felt sound like scuffing two chalkboard erasers face to face. Not the end of the world or anything but VFO B makes only the faintest of hissss from the felt and B acts perfect. The Best tension I can get for the A knob isn't as good as the VFO B which feels darned good to rotate. I did rotate each of the shafts before assembly to be sure they were OK & they both rotate with zip friction. I could forego any friction at all & it would be fine & easy to rotate but it would be a constant annoyance when I bump the VFO & then be moved away from a frequency I'd narrowed in on. Since I will forever be using VFO A, I do need it to feel natural. Gary KA1J > Well, I'll jump in here. I had the same problem a few months ago when I > assembled S/N 1889.
