[AMRadio] need 2 watt non inductive resistors

[Jim Candela]

Tony,
 
  One other thing. A valiant can put out 150 watts of AM carrier, and a T-Bolt should be able to put out 400 watts when the 4-400's are running flat out at maximum plate dissipation (back to that 33% efficiency again of AM linear amps). If you back off the T-Bolt to ease the burden on the tubes, then maybe 300 watts output. So this approach gives you 3 db power boost above the Valiant. Consider that even if you de-tune the valiant to 75 watts out, you still need to get down somewhere into single digit watts to drive the T-Bolt. Looks like a 10 db, or more pad is required. Is all this trouble worth it to you? An AM rig with a single 6146, or 2e26 in the output may be a better approach to drive the T-Bolt. Good luck with your project..
 
Jim

i need to build two pads and will need the following resistors all 2 watt
10 - 1200 ohm
4 - 470 ohm
10 - 4700 ohm
12 - 220 ohm
4 - 68 ohm
12 - 820 ohm

tried mouser digikey and aes. anyone have any ideals where i might find 
them or if the new type resistors that they carry will work. they have to 
be non inductive . dropping the power out of my valiant and other 
transmitters to drive my thunderbolt.
thanks 73 Tony
