Starting the next one
The row of holes down the middle is exaust for the fan in the back of the chasis. I shouldn't be needed, but it would be nice to keep the caps inside cool.

The extra holes and grease spots were from r theta test. I wanted to be sure these things would keep cool.

Nice job!

Your front panel would also be great if you polish it mirror like!

congratulations on you work!

This forum has been lacking photos of innards lately, so I'll show you what I've been up to. The big ugly IE's hummed and buzzed and didn't give high enough rail voltages, so there out. There was also a lot more supply ripple than I want ( 2.5V ). I called Avel Lindberg and orderd a pair of 1000 va 50+50v toroids. The price was right, but they're made in China. (Not to knock our Chinese members. They They know that they keep the good stuff and send us the trinkets and crap.) Yuck. The wires seem a bit small for 10A but they will only see 5A load.

This layout will give a much cleaner looking inside. I may put a slab of steal under the driver board if I hear any noise from the tramsformer. I'm also going to put air core chokes on the front corners of the Al subfloor the toroid is mounted on.


Sweet home made ground bar, eay.

PSU has fred rectifiers, 68000 uf 100v monster caps, air core chokes around 6mh 1ohm then 34000 uf 74 v caps (per rail). Should get the ripple down where I want it.

Those are not the chokes. and they will mount flat with nylon bolts the the holes near the corners seen in the other post.

My wife leaves town and I can barely keep myself fed and in clean clothes...

When I fantasize how my amps will look when I someday build them...

Hi Brian,
I want to ask you something to do for me. Please call my wife to visit you. This is the only way to catch some extra time to finish my Aleph. (he, he, he)
Nice work and good luck to listening your amps.
Greetings from Belgrade.

Very nice and robust looking amp.
You remind me of Magritte, or is it a tipo?
