There is the book about production of quartz crystals for WWII, title "Crystal Clear".
"Good-All": man, i haven't heard that name in decades, snd most likely would not have thought about again in this lifetime! Around 1962 i built from a circuit in 'Popular Science' magazine a one-transistor radio. I had no mentor and no advice of any
kind. I didn't know you could get parts free from discarded radios and i didn't know that when the text said to wind the tickler coil with #38 wire, you could use a couple feet of whatever thin wire you could find. So anyway i ordered a spool of #36 and a
spool of #38 wire. I had for many years thousands of feet of extra, very thin wire. I also ordered from Allied, two capacitors and one resistor. ( High volume order. ) Anyway, the one paper wax tubular capacitor was "Good-All" brand.
I recall thinking, that's not an impressive name; it makes me think "Good Enough". Which i suppose it was anyway.
