WTB High powered Load bank for amp testing

[Zero Cool]

years ago i found a BIG heatsink loaded with some high powered 4 ohm 250 watt resistors, perfect for a configurable load bank. Building a new lab for work and I am on the hunt for something similar. anyone have any big 4/8/16 ohm high powered resistors laying around, etc?

Not that useful, but 10 years ago the axman in St. Paul had a bin of them...

yup, 10 years ago, ABC Industrial, Axman, Acme lots of good surplus stores in MN, not so much anymore.

Oh wow. Axman. Those were good times. We're losing our surplus stores in CO, too.

Take a look on Pete Millett's website. He has a load box and gives a source for relatively inexpensive load resistors.

I use MP9100 TO247 resistors $$ but low inductance and worth it for that reason.

A friend uses the elements of an old electric fire - just tapped off with a jubilee clip at 8 ohms.

Heatsink wise look for old tig welders that's what I use for my dummy 10" x 6" x 6" approx tunnel HS, I have another you could have but shipping to the states would be mucho expensive.

Ali clad resistors are cheap, not convinced of the need for non-inductive types unless your testing amps at VHF.
