[TenTec] Corsair VFO

[Clark Savage Turner]

My suggestion: take the PTO out (not a hard job, just requires a little 
care and patience) and put it on a clean sheet of paper on a clean 
desk.  Disassemble it, observe its workings (you'll need to remember 
details later!), make notes regarding the small parts and just get the 
feel for how it works.

Thoroughly clean all the components (I use a "self cleaning" bearing 
lube from a bike shop, cleans out all the bad stuff) and dry them off 
really carefully.  Re-lube (again, bearing lube from a bike shop will 
do quite well) and reassemble right there on your desk.  Put on the 
knob and get the "feel" - see if you now like it.  If not, take parts 
off and reassemble till you get the "feel" you want.  The number of 
washers in the rear are critical to the "tightness" of the operation, 
and there are other parts that can be moved a bit here and there to 
alleviate "lumps" in tuning (the little washers may be dirty or need 
some lube, the pins may be stuck in too much to one side and binding).

I've found that by just playing with the PTO once, noting my sense of 
the whole mechanism, now I can pretty much rebuilt a PTO to feel the 
way I like reliably well, usually with no parts replacement (though I 
keep a spare rebuild kit around, buy one from Ten Tec just to have 
nearby!)
