Hi,
I've now finished my F5m amplifier. I built it into the large Modushop 4U400mm enclosure. (PassDIY enclosure)
With 0.66V across the 0.47 Ohms (=1,4A) , the heatsinks barely get warm.
What's your experience with the larger enclosures?
What would be your recommendation?
How high can I go with the current?
Best Regards
Barossi

^ That sounds about right. Nelson put estimates for temp rise in the article.
You can always try a little higher, particularly if you have lower impedance speakers and/or if you just want to see if you hear a difference.
The "rule of thumb" is to not to exceed 35W dissipation per device, but I'm sure people have pushed them further.

Great idea. I'll do it
By the way have you noticed that the output wires on the Antek 3218 are 12AWG but the holes for them on the power supply PCB are 12AWG max. It's a shame to have to rig an adatation to the smaller wire diameter. Maybe a possible correction if further runs of pcb are made.
Mine is in a 3U 400 mm and it doesn't get hot, toasty but not really hot. You should have plenty of sink!

I recently build the F5, does the F5M sound different and is the Aleph J still the best sounding class A amp to built?
The new boards for CPU fan cooler arrived and were set to 1.4 Amps. It has two inputs, one with a filter 1.2k 47k 470pf a perfect square wave test and one as the original 10k 47k selectable with jumper.We are waiting to hear the amplifier.
