Hi Circlotron,
Cool looking amps. Way to go. I assume this is the stereo prototype.

Now I can see! Looks great, Jason. I like the way the fets are underneath the pcb rather than having a right-angled bracket sandwiched between the pcb and fets. Means the board can be screwed down good and solid to the flat heatsink surface. A minor thing perhaps but it helps make a good amp better. Now we must have the subjective sound report please.

Go N-channels Go! Yes! Yes!

The pcbs look great.
but the fets under the board are hard to control when screwing.
Very good job.

 

[Circlotron]

What do you mean "hard to control?" Do they twist around or something?

Fets under glass

Does anyone think that the PCB insulates the Fets and causes them to run hotter?

 

[jleaman]

yeah because the plastic or what ever it is doesnt transfer the heat..

J' that is why i did it the way i did..

Nice work Jason! I'm sure it will sound as good as it looks...

Coincedentally, I finished my N-channel too today. It's a modified version with +-40V supply rails and IRFP450 devices. Sounds excellent!

Good luck!
