Also interested in a balanced PCB if you decide to produce them again.

2) For my headphone amp i would need 1 SE board and 1 PSU

Can you also supply the matched FET's with the PCB's? How can i order?

Yes, I can sell the matched JFETs as well. Right now, even my SE PCB stock is getting empty. I will order new boards immediately after 1st of January.

To place an order, please send me an e-mail (on my web page or thru PM here /I have only e-mail PM activated/). I will let you know when the boards are produced.

Thanks,

Pavel,

did you ever use the ALPS in shunt mode with these boards. Would also be an advantage for the balanced boards, you would only need a stereo ALPS. I do this in my cross over, works very well and pot is not in signal line.

Looks like this

(+)IN---R1---------R1 ---OUT(+)
|
R2 (id needed depends on pot)
|
10k ALPS
|
(-)IN---R1---------R1----OUT(-)

regards,

PS the ALPS is now replaced by a stepped attenuator because the channel matching of the ALPS is not good enough for me.

Harold,

yes, this is one of the possible options. One of my customers is doing that same way.

Dear Pavel,

do you have boards available at the moment? Could you send me a pm with the cost (including shipping)?

regards,

Harold
