Ordered a TV power supply board from them today.
I'll know in a month how it turns out.

Couldn't find one in the states.:(
This was less money and free shipping.

tnx

Sometimes it takes 40days and sometimes a week.
Could not figure out why the package comes sooner by china post and china post is worst than hongkong or singpost

Another good way to create power resistors at the 10 amp level is to use (heatsink mounted) redundant power transistors, connected.

Here is a bidirectional one, you only need one transistor for unidirectional.

Note this is a purely passive circuit.

I think resistors are the simple approach.
No power needed and no hassle.
Just connect them is series or parallel or both.
