[GreenKeys] enlighten me regarding Model 19 rectifier

[COURYHOUSE at aol.com]

Yea Eric I saved a photo  of that ....  that is a massive  power supply.  
our  19  had been converged   so   it did not have that...  I have some  sort 
of   black supply  but   about a third of the size.
 
 
please keep it intact  if  you  can ,,,,, the innards  seem  really 
clean...  just  hook into the   selector   from there tu...  to  run  with  modern  
stuff.

Ok,  I don't have this thing in my possession yet, but looking through  the
documents and pictures it appears there is a REC-30 module which looks  like
it weights about as much as my car. Seems to be a thyratron based  
rectifier/
regulator circuit, plus a big transformer with a bunch of  different taps 
for
different input voltages, etc. 

What is it for?  The printer and TD seem to have plain 115VAC motors. I 
naively 
assumed I  could just string the TD, 15, and keyboard in series with my 
existing loop  and fire away. Is the purpose of the REC-30 just to provide a
local loop  supply so you can, say, print from a tape, or punch from the 
keyboard,  without needing an external loop supply? And maybe also step down
AC mains  voltage so you can run the 115vac motors off 220? 

I'm sure the mercury  vapor tubes are pretty to watch, but I feel like I'd
be happier putting the  150 lbs of steel in a closet somewhere and using
my existing loop supply.
