KNOBS:

Alan / KC9YS, New Drake pointer knobs (with the set screw), individually for $4 each or a set
of 9 knobs including a new preselector knob for $35. As you know, you can use
these knobs on the plate and tune controls where there used to be a spring. The
setscrew allows you to set the knob just slightly away from the panel to prevent paint
damage. TR-4 & ‘B’ line main tuning knob $20. These are New stock, not NOS. To
make a purchase or for further information please e-mail at the link listed above or call me at
630-879-1132. Alan / KC9YS Email: [e-mail]

KNOBS:

Fred Freeman / N8BX, The original Drake R-4 and TR-7 Plastic knobs weigh in
around 1 ounce.. These premium USA made knobs weigh 8 ounces and they tune
just wonderful. A spinner makes for fast and easy QSY. It actually makes frequent
band changes pleasant and you soon forget how long it takes going from each end of
the VFO. This knob is for the ham that uses his radios daily and wants a beautiful

weighted knob with a luxurious feel. Installation is easy and all hardware is
Stainless Steel. Everything is CNC Machined from billet stock right here in
the USA. The set screw that holds the knob in place is a flat tip style (no
marring of your VFO shaft) and the spinner is long lasting Delrin. These
knobs are first class all the way. I am so sure you will be pleased I will
100% guarantee your satisfaction for 30 days or you may return it for a full
refund. P.O. Box 249, Caledonia, OH 43314 Phone: [phone] Email:
