Haven't built another yet, its in the works....next one possibly water cooled. Listening to a 20W SOZ with FE127E...an amplifier definitely worthy of building a monstrous chassis for, simply amazing!!


My diy safety rules are as follows (they require some level of "thinking", not enough to break a sweat though):

1.) Keep ALL heat generating apparatus in a metal enclosure.

2.) Never leave the room.

3.) Keep a fire extinguisher within easy reach.

4.) wear safety glasses

You can add a dozen more, but if you follow these, you can take down an amp without taking down the house.

So are these Peltier effect TEC modules? Closed loop temperature control.
Cool!

I experimented and made a few myself, the one's I bought, are basically an aluminum plate with copper piping clipped into them. 0.0110 C/w @ 1 GPM. I'll post a few pics when I find the cam.

Homebrew:

Don't quite know what to do with this one.....maybe slap some big aluminum power resistors on there for a SOZ.

Homebrew (in the works):

This one should be a bit more efficient. 12"x3"x0.5" - 0.125" holes
