Hi list,


An other economical solution is a MMR; couple of month ago I find
a batch of 50 resistors 15 K* 25 W for $5.00 CAN 9 ( around $3.00
USD ) with 14 parallel you end up with 1.07 k* 350 W perfect for
Terry NST protection filter see this;

You need a heat resistant holder I used copper pipes this way I
have a large surface for solder and the solder do not melt in
use. The resistor assembly in the left is 4.3 k* that I used in
my preliminary MOT supply test.

The resistor are not perfectly equal in value they are rate at
10% but with measurement they have around 7% difference in value
that mean some resistance in the assembly are heating more than
other but after testing with power the difference is acceptable.

Cheers,

Luc Benard

I think I might have found an alternate source. Would these be
ok?
