[TenTec] Centurion

[Richard Detweiler]

No,  you don't 'need' any extra cooling,

Many hams have built a tube warmer,

We just use a socket and filiment transformer with the voltage set properly. 
  mounted in any old chasis that will hold em..

Hoever, for some of the hotter filiments, I've been known to put a box fan 
at the bottom of the warmer blowing up,

Best wishes,
