Gentlemen, I have a pair of Mr. Nelson Pass A40 ClassA amplifier PCBs, which I want to offer you.

The PCBs layout is done by myself.
I have included the frontend, the backend and a simple C-R-C PSU on the PCB.
The PCBs size is: 236x85mm.

I am using "current" transistors as replacement for the transistors that Mr. Pass used in his original design.
I use - for example - MJH628X Darlingtons as Output Transistors, KSC2690 and KSA1220 instead of obsolete MPSL, …

Find attached an image of the PCBs, a "PCB - look-through" and the schematic.

I offer the pair of PCBs for 20€ (shipping - without tracking ID - and PayPal-fee is included).
If you are interested having the PCBs: give me a PM.

Best regards - Rudi

Gentlemen, I have done revision 1 of my A40 layout, which is a bit more compact (189 x 82mm), and I will order a small couple of PCBs tonight.

Three pairs are already assigned, two pairs are free to order.
The price for one pair incl. shipping (shipping is without tracking ID; the usage of tracking ID costs an additinal fee of 3.50€) is 20€.

In case you are interested: give me a PM..

Best regards - Rudi
