I smoked the "Line Adjust" rheostat in my TV-7D tube tester recently and
so far have not found a replacement. I've got it by-passed now and am
using a variac to set the voltage level.
If anyone has a tv-7 junker, I sure could use one. It is 200 ohms in
value and 1 1/2 inches in diameter.
Please reply at my email address on QRZ.com.

Thanks

You want an Ohmite RHS250 rheostat. 250 ohms, 25 watt.

Galco has them in stock for $30 or so:

Or you can take your chances with Newark or Allied and possibly get a much
better deal depending on how well you know your Newark or Allied rep.
