[Milsurplus] To be 90 or not to be...

[Charlie L.]

Since the RAK/RAL has come up, what is the deal with the 90 volts?  I built
a supply for my RAK which I acquired first and put in a  regulator circuit
using a 90 volt reg. tube that I just happened to have, it glows orange,
but the radio worked just fine with or without the 90.  My other supply for
the RAL is the correct supply for it and got that from Brian KN4R.  The
only problems so far after a decade or more has been replacing the 1uf caps
and other large bypass caps, tubes I have found plenty of.  That one
stacked cap under the chassis might be a concern, but if need be, could be
subbed with individual bypasses if it ever fails.  The RAK gets its most
use during the winter when I am looking for NDB's, using it or a Mackay
128XX, the RAL gets used throughout the year.
