[ARC5] Meter. Feet, Pounde etc.,,

Fri Oct 1 09:37:51 EDT 2010

When I first started working in analog IC design, we used to have a rule of
thumb.  A discrete solid state circuit rendered in IC form would end up
using 7 times the number of transistors to do the same job.  While we didn't
have a rule for tube-to-discrete transistor conversions, let's just say for
sake of arguement that was roughly two times.  Do the math and then mulitply
one final time for the extra bells and whistles that invevitably get added
and it's not hard to fathom how the same basic transceive function
implemented with vacuum tubes ended up consuming so many transistors and
IC's.  Another factor is the heater burden of vacuum tubes, which greatly
encouraged set designers of old to "get clever" and do elegantly simple
designs.

BTW, converting an old CB to 10 or 12M is fun.  Maybe not practical anymore,
but still fun good buddy.
