[TenTec] Omni D - possible VFO rebuild in my future

[tfr001 at myfairpoint.net]

So I have an Omni D. Lately, the VFO knob has been getting much stiffer. It will sort of freeze wherever you leave it overnight... the next day, it will be very hard cranking and it seems like you have to crank it many, many more revolutions just to get it to move freq at all. If I crank it up and down the entire bandwidth, it will be servicable for the day, but next day back to the same thing.

So am I looking at a rebuild here? Or maybe just a re-lube?
I have not attempted to open the VFO before this... and sort of dreading it now.
