Jan made individual articles available for sale. https://www.linearaudio.net/I’d like to know the current requirements is it +/- 15Vdc at 150mA per channel or less ?
Ideally I’d like to use a 19Vdc laptop supply, is there a well known (not noisy) way to get from +19Vdc to dual polarity +/-15Vdc supply?
Thanks
Eric
For a +/-15VDC supply search DK for a DC-DC converter, 2 outputs, 7 watts, Murata or Meanwell. The converter, if necessary, can outboard LM317/337 to remove a lot of switching transients. Make sure to put a choke on the input to the DC-DC converter. Marsh HPA will run well on +/- 12VDC

That is no longer the case.
The paper copies at Amazon are also printed to order, as far as I know.
The entire volume is available in a USB stick.

Over the years, he made a loss at the end, after all the effort.
Only doing this for love. My deepest respect.

I actually sent 2.9 Euro as mentioned on the website to Jan and the same day I received the Marsh HA article in PDF format.
What service.
Won't buy him a coffee at a Bistro.
How we miss him here,
