Question about the Aleph P 1.7

roger-k · 12th November 2005, 03:26 PM

I want to build this preamp: Aleph P 1.7

There is three capacitors in parallel, each at 10uF.
Is it possible to use only one cap at 30uF, just to save some space?
What voltage should these caps have?
I have seen many pictures of the aleph p 1.7, almost all people use polyester caps. Is it possible to use other caps just to save some space, for example bipolar elektrolytt caps?

I know this is possible but I mean: Is it possible to do that and still have the same sound picture and the same quality of sound?

Is it necessary to use heatsink at the output transistors?

Any who have a component list for this PCB-board?

If you have that PCB, you also have the component list as it comes with the PCB.

Kristijan is a nice guy who always anwsers if you mail him...

Soon I'am finish to draw the schematic. After I will draw the PCB-layout. (I'am using the Eagle).

But I need som help to choose the 10uF caps.
What about Wima MKP4, 10uF, 250VDC.
or:
Wima MKS4, 10uF, 100VDC.

Any comments?

Use the MKP's if you can fit them in
