[Hallicrafters] Soild state vs Tubes

[Glen Zook]

In general replacing the rectifiers with solid-state
is a matter of personal preference.  However, with
certain units, especially the HT-32 and HT-37 models,
the power transformer is operating at the very "ragged
edge" with tube type rectifiers.  Replacing them with
solid-state definitely lowers the "load" on the power
transformer and results in considerably longer life.

On most other equipment I leave the tube type
rectifiers in place.

The whole purpose of  restoring a 60 or 70 year old
radio is to  experience the glow and warmth of a
thermionic vacuum tube  !! If you want  to use solid 
state replacements then you might as well remove all
of the tubes  and insert transistors in all the
sockets(of course with the proper voltage  dropping
resistors !) that would defintely reduce ALL heating
and load on the  power transformer !!
