Why would you want to waste your time?
It was a copy of the PARAGON phono, basically.
I think its popularity lasted about as long as Lee's magazine which I probably have laying around here somewhere.
I remember it being very unstable which was likely the power supply but isn't there a fundamental problem using high mu tubes in cascode?
