[sdiy] ARP Avatar patent

[Mike I.]

Listers:
Stumbled on this by accident - go to www.pat2pdf.org  and fetch patent 4300431 (about 600K download).

It may be the patent for the mystery epoxy-encapsulated P-V converter module in the ARP Avatar. The author (DeRocco) is one of the guys who designed the Quadra phaser . The schematic includes  the ARP voltage-controlled Norton amp integrator,  which is also used in the 4072 and 4075 filters. ARP is not mentioned anywhere, but it appears there is a connection.
Cheers, Mike
