Ken,
I replaced the elastic band on both of my 238s with miniature stainless
steel springs. Gardner Spring, Inc. part # V17C. They are .130" OD x .0162"
WD x 4.0" OAL. I found them at a local hardware store (the old fashioned
kind of hardware store that has everything). I used doubled 15 lb
monofilament fishing line to tie one end of the spring to the left bottom
panel screw (same place the elastic cord is tied to), and another length to
attach the other end of the spring to the dial pointer. Works perfectly. The
spring has a very slight amount of tension on it when the pointer is in the
full right position. When the pointer is in the left most position, the
spring is fully extended and comes within a half inch or so of the right
hand bottom panel screw, so it stretches across the bottom of the tuner.
I went through several restringings of the elastic cord, and finally decided
to do something better. No more problems!
