[R-390] Trouble Shooting R390A/Backlash

[jonklinkhamer at comcast.net]

Hi Folks,

Just wanted to update the group on my restoration of the R390A. The 1/8amp fuse was replaced and the radio came up singing. It was like an old Toyoto commercial "Oh, what a feeling". Apparently it was a weak fuse, most likely from the mid Sixies. Thank you for all your comments. 

I'm focusing my attention now to the RF Stage and have a question concerning backlash. I noticed a certain amount of backlash while turning the KC knob counter clockwise. The lower and upper frequency ends seems to move about 1 to 2 clicks while the mid freq range, approx 300 to 500 appears to move as much as 4 clicks. Can anyone point me in the right direction as far as adjustment(s) to correct this? Hopefully nothing is warped.
