The original bushing was pretty hard as well. If it is the ribbed gray
material, try sanding the ends to roughen them up a bit. Then be sure to
apply sufficient pressure when installing the knob. The bushing doesn't
really have to be soft to work, just not "polished" on then ends. This
will fix about 80% of them. The heater hose works, but I prefer using
the clear poly tubing available at hardware stores by the foot. Bottom
line..... The material really isn't all that critical. 3/8" id, 5/8" od.
What is that, about 95 mm id and 160 mm od?
The TR-7 used surgical tubing, the translucent, amber colored soft
rubber tubing. It works fine as well, but turns a gooey, dark brown
texture after a few years.

Hello Drake List:
My R4C needs to have the rubber bushing (which resides under the VFO
knob skirt) replaced as it is now rock solid. I have read WB0IQK’s
recommendation on using a Goodyear Horizon ¼” 200 PSI W.P. hose.
Has anyone successfully used this replacement technique before and are
there any other alternatives such as NOS replacements?
