NCX-5 Part

Long shot- but I am looking  for the antibacklash spur gear on the main tuning cap of the VFO.
Tnx,

Dale --

I wonder if National used a New England spur gear mfg. (now in North Carolina) and
it was an "off-shelf" size (in catalog)?

Thanks Greg. I was looking at their catalog last night and w/o having the gear to look at, I believe it is a 20 degree gear with a 32 pitch/ 1.5" diameter and 48 teeth. Another ham is going to send me a pix of that area of the VFO. If I buy one, I guess I'll need two and have to mill slots for the backlash springs.

Once I confirm the gear- I might be able to find some cheap in the hobby area of eBay- model cars etc. Small Parts want around $20/gear

The real shame is that I sold an NCX-5 parts rig a couple years ago. Lesson learned- never sell anything.

Tnx,
