Aleph -

It was going to be an Aleph 3, but it ended up with 17.5 volt rails.

Thanks to Nelson, Jam and George for the extra parts.

Fairchild output devices, 350VA victoria magnetics 15-0-15 , 36000 uf. , .2ohm, 36000 uf. per rail. It sounds very nice. Bias 1 amp per output.

Nice job Mike,
What speakers are they driving?

You should try to make some slightly better pictures and send them over to PassDiy.

Very nice! I like your wood front panel...warm, reddish tone. Warms up the usually cold-looking (but warm to the touch) metal chassis

Nice Aleph Mike!

Is it made on MiniA boards or ??

Looks like the heatsinks are taken from the old Heathkit amp that dates from the 70's; same ones I used on my Zen4. Mine work great on the Zen; how do they do on your Aleph ?

I gave away all my mini boards. If eveyone I sent them to builds an amp you should see quite a few. Someone was nice enough to send me a set of Brian GT boards.
I am driving some little Cambridge soundworks speakers along with mini-pipe-o.
The heatsinks are only 40 deg. This amp will see more work before I am finished with it.

I built five Mini-A's and kept the one I liked the best. Some Aleph P's next and maybe a PLH after that.

What type of wood/finish did you use?
