Gentlemen, I like and offer you 3 sets of PCBs (see image 1) consisting of:

1) a pair of Nelson Pass ACA - PCBs, implementing TungstenAudios "Premium ACA" modifications
Refer to TungstenAudios thread: https://www.diyaudio.com/forums/pass-labs/328357-aca-amp-premium.html

My pair of ACA-PCBs also includes 2 tested pcs. of 2SK170BL transistors.
The "Premium Parts ACA" works "flawlessly" and sounds absolutely nice.

It is powered by a "CapMX - PSU", designed by JKuetemann.
Refer to this thread for information about the used CapMx - PSU:

https://www.diyaudio.com/forums/pow...lified-mrevil-pmi-capacitance-multiplier.html

and read "Rod Elliotts Project page 15" to find out, why a CapMX PSU is the best suited PSU for the ACA.
I will of course give you all needed documents (schematic, layout, BoM, drill-template, ...) for my ACA-layout

Images 2 and 3 show you my "Premium Parts ACA".

2) a BJT - matching PCB
I have been in need of a PCB to match "big" BJT-Transistors and the N-Fet 2SK170BL. The result is shown in pictures 4 and 5.

3) Last, but not least: I include my version of the B1-Buffer in this offer.
Refer to Image 6. The Buffer is driven by a dual LT3082 PSU.You need 2 pairs of well matched 2SK170BL.

I will offer you a set (consisting of the 4 PCBs and 2 pcs. of 2SK170BL) for 18€; unregistered worldwide shipping is included.
I have 3 sets left.


If you are interested iny my offer: give me a PM.

Best regards - Rudi
