Found details of this project in my paperwork. I think it is from Théoric - apologies to DBug - but this has English translation, nto found in ThéOric downloads.

Has anyone built it? Does it work well with Cumulus ???

Thanks! Nice article and I'll try it. Actually it should be the same as 'internal' PH2 amplifier.
Here interesting and bit strange is the usage of 3 buffers in parallel - normally such connection
should be made with 'open collector' elements (for instance 7407) and common resistor to Vcc.
Using 74126 can lead to self damage of the chip, but it will not burn the Oric :).
