[R-390] Old HSN Mods

[Tisha Hayes]

Going through the old HSN archives you find ideas for mods that we would not
do today (transistorizing a R-390A, <gag>). It is interesting to look back
and see some of the original rationale that went into some of the other mods
we accept as good today. I took much interest into some of the intermediary
circuit designs to fix the AGC action and the early discussions on the
filters. It helps me to understand the thought process and how it evolved
over time and multiple editorial contributions from all of the subscribers.

Reading the HSN archives and you can smell the soldering iron cooking in the
corner, next to the lava lamp.

Sadly so many early contributors have gone SK. Continuing to pass on their
written legacy is a type of immortality for those of a bygone era.
