Selenium Rectifier (continiued)
- Althoug my problem is not totally solved , a huge step in the right
direction was taken yesterday when i purchased an olde book called "Audels
Radiomans Guide" published in India ! circa 1966 (still older than me :))
In a word this book "rox", never have I read a more practicle,informative &
interesting "technical" manual , anyone who needs a good reference book or
just needs some quality info on the basics of how everything works , should
have one of these.Best $8.50 I spent in a long time.
It has a section on selenium rectifiers , how they are made how thay work
and what there applications are, I should be able to reverse engineer my
2nd mystery box quite easily now.
Also in the back of the book they have several "Nomographs" <ohms law ,
parallel resistance & reactance> the reactance chart seems very handy for
calculating the values of Inductance Reactance Capacitance & Frequency ,
range of 1 cps to 1000 Mcps ,I have never seen these graphs in any modern
publications , this is not the first time I have found something "new" in
the back of an old book.....it's almost like "they" are trying to keep
knowledge from me.
A quick cross reference with this "new" textbook and some of the "old"
Tesla notes I have , has already filled in a few gaps in my understanding
of how things _really_ work & as usual raised a few problems that I can nut
out in the lab.....
It almost makes me want to get a slide rule and learn how to use it.
How many other secrets are being kept from me ?
New text books suck , grab the old ones they have more information in
them.I shudder to think what would have happened if I was given this book
at age 13 when I was first getting into CB radio....
More importantly is their an equivalent "mentality" syle textbook that
covers Chemistry ?
Looking at the Past , to See the Future.
