Hi Bruno,

I'm interested in some boards as well as
power resistors/MOSFETs.

I'm starting to read those threads about Aleph-X.
BTW is VR101 200R??

Cheers

TS

Hi all,

well, as for the input caps, no way!!!
They wouldn' t fit on this board even leaving the heatsink out, unfortunately PP caps are wayyyyyy to big. Using MKT caps would make things easier, but I' m not sure the sonic results would be as good as with PP...

TS Lo:
VR101 is 50K.

Cheers,

Bruno

Hi jleaman,

the output boards are daisy-chainable, there are also pads for screw terminals with a 200 mil step for this purpose (and, of course, normal soldering pads).
As for the group buy, well... I do not know, it depends on how many people are interested.

Cheers,

Bruno

I believe 4 is the minimum. Have you looked at the Aleph-X Wiki ?

A lot is answered there.

Blessings, Terry

Default Version 5 - Input caps

Hi all,

well,version 4 has been trashed, don' t ask me why...

I redesigned the board completely and now I have found the place for two PP input caps

The two resistors between outputs and ground (33R 3W) will be mounted on the bottom part of the board, OR stacked above the big output resistors.

Any comments?

Cheers,

Bruno
