Hi ezra pound,
Wow, resurrection of memory does exist, OC72 & OC71 as a complimentary germanium pair, how things have changed. I still have some original CMOS 4001 in conductive non static foam and my earthing wrist band too. i feel very happy to have experienced the creation and development of electronics in its raw form, I truly loved working with valves, the purity they gave in audio, for example, was exemplary, it brings back fond memories of me playing with my AC30 guitar amp. I actually hacked my AC30 and installed a push pull output stage using two 6V6 valves, what a wonderful sound !!
So nice to find our kind are still around,
Kindest regards,
John in the UK
