Are you looking for one pot, or are you looking for two pots? Following the thread, it's hard to decipher what value/wattage pots you need.

The 25 watt would not be a pot, but a rheostat - Ohmite, Angstrom, and Clarostat are the big three when it comes to rheostats. Angstrom is now part of Vishay, and their 25 watt rhoestats are smaller in diameter (38mm)than Ohmite and Clarostat devices.

If you are looking for a 300 ohm, 25 watt rheostat, the Angstrom RT25 series are what you need - 350 ohms is standard, but you may find a 300 somewhere. Allied Electronics lists Vishay/Angstrom as a line they carry. Mouser carries a 220 ohm, and a 470 ohm, both a bit away from your 300 ohm value.


Cheers,

You can also check fleabay or some of the surplus places to see if they might have what you're looking for.
