Hi all,

I recently received from Ten-Tec a new dial cord and elastic stretch 
cord for my 238 tuner. An instruction sheet came with the parts, which 
differs somewhat from the DIAL-STRING ROUTING DIAGRAM in the manual for 
the 238.

The most significant difference is that the new instructions show a 
"single pulley" at the upper right hand corner stand-off. This is a 
great idea. I am sure the elastic cord will work much better running 
around a pulley versus just being dragged around the stand-off.

The problem is that my 238 has not had one of these pulleys as long as I 
have owned it, and the manual does not indicate that it was original 
equipment. Ten-Tec did not send me a pulley. I did not ask for one when 
I placed the order, since I didn't know there was such a pulley. It 
seems like there ought to be one on the lower right stand-off too.

There are a few other differences on the instruction sheet. It shows 
"brass stand-off" in a couple of places where it looks like aluminum on 
my 238. The elastic cord gets tied to the SWR SET potentiometer shaft 
instead of to the lower left hand standoff.

I wonder how many versions of the dial cord string routing there have 
been over the years? I know they have abandoned that method altogether 
in the newer tuners. And some people have made their own modifications 
using a spring instead of the elastic cord.

I guess my 238 will not be back in service until another care package 
comes from Ten-Tec.
