I was wondering what the value is on the pot in this amp amp I have one that has been replaced but its already burnt out and it was never the right value after it was replaced.
 

There's a reason it's burned out. Nobody seems to use a control big enough. The small half-watt controls don't last long as a rule. The 2-Watt control used in a D***M*** tends to last a while, but only because they include fixed resistors around it to share the load.

The Texas Star amps can be a pain, since there's ALMOST enough room for a larger, 2-Watt size control.

Odds are that your control was either 100 ohms, or 250 ohms. I always recommend turning it all the way up, and using the radio's carrier control. This way it lasts a lot longer. That control tends to wear out only when you turn it down from full clockwise.

If you know where the three lugs on the control were connected, you can probably get by using a 100-ohm 3-Watt or 5-Watt (NOT wirewound) fixed resistor, with the wiper wire and the clockwise-end wire tied together at one end of the resistor. The other lead goes to the wire that was on the counterclockwise lug. Even if your radio gets this resistor hot, there's no moving contact to burn out, like there is in the original control.
