So how much for the board and components? 22$?

Thanks

digi01 · 9th March 2004, 04:36 AM

yes,the board and components is $22 USD.Make a stereo headamp,you need two sets of these.

NOTICE: the components is not include the transistor Q1/Q2/Q3.

what kind of resistors are they?

digi01 · 9th March 2004, 06:55 AM

OHH,I have written a mistake.it should be the 'resistors'

There are two kinds of resistors.the small 1/4W resistors is standard metal film,the big resistors R10\R11\R12 and R18 are DALE type.

If some of your components are bigger there is enough room for modifications.
This is a experimental version,I use some different components inside.

Hi Marcello,Thanks for a very fine contribution.ZEN headamp is my first project of your design.Do you hope that zen is as one kit? I wish this amp can be more diyers make,just like PPA ,gilmore and such these.I do not have experience in this action, your view?

Regards-digi01

Hello digi01, for me there is no problem at all.
If somebody will ask me again the project's PCBs, I will redirect them to this page.
Cheers
