Barry,  (How many Barry’s are there?),

The “non-A” has its challenges, but some feel it is easier to overhaul.  For instance, many of the capacitors are going to be still just FINE after all these years.  Also there is the fabled Green Gear.  And the voltage regulator system.

My suggestion is that you put a fan on the outside of the frame to blow air past the 6082 series regulator tubes (you do have some spare 6082’s right?).  I have a picture of the one I cobbled up that shows how it is made and how it fastened to the existing bottom plate and frame screws.  It makes a HUGE improvement in the temperature of the regulator section.  Glad to send that picture to anyone interested.

For anyone living within driving distance of the Connecticut River Valley in Western Mass, I can recommend a source for  superb authentic Polish Kielbasa.

For anyone who might work on a glow in the dark meters, or military grade regulator tubes, I offer this:


     Morgans Rule for Radioactive Meters and Voltage Regulator Tubes:

     DON’T’ BREAK THEM OPEN AND EAT THE INSIDES.
