[TenTec] 238 Tuner question

[Joseph Koppi]

Vince:  I am experiencing a similar problem with my Model 229 tuner.  It
turns out that the contact wheel has a worn or slightly oversized center
hole.  As a result, the wheel does not fit snuggly on the tension bar that
holds it against the coil.  It wobbles on the tension bar and, at times,
binds on the coil.  In my tuner (and I took off the cover to observe this),
the ill-fitting wheel binds on the end of the coil with the wider turns, and
when it does, it jumps off of the winding, requiring the tuner to be opened
and reset.

Ten-Tec service suggested using Deoxit to clean and lubricate the wheel and
tension bar.  They also told me that the bar and wheel could be purchased
apart from the entire coil if I wanted to replace just those parts.  Or, you
can buy a new coil for $62.

I'm going to try the cleaning and lubrication route first.

Hope this helps.  Good luck.

Joe, WØSU
