[AMRadio] need 2 watt non inductive resistors

[Jim Candela]

Tony,
 
   There was a guy at Belton that had attenuators for sale ($1.50 ea), and they were for what you are seeking. These were 3DB attenuators with an RCA input connector, and BNC output. It looked like it was capable of dumping 20-30 watts. I have one but mine is a keeper, sorry..You probablly need a 6 db pad for the T-Bolt. 
  I just looked into Digikey, and there is a nice option there. Ohmite makes power non-inductive resistors in a insulated TO-220 package. These need to be bolted to the inside of a aluminum box, or heatsink. They have a 25 watt version for about $5.23 each (Digikey catalog). Now consider that your list is for several 2 watt resistors stacked together to make more powerful resistors. With the Ohmite approach you only need three resistors (pi or T attenuator), for about 15 bucks total , and a aluminum box. Here is the ohmite link for these parts:

Regards, and Merry Christmas to you, and the whole group,

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
