Congrats Eric!  What a light show!  The  machine   has a great  home!
 
We are still  battling  with our   19... ours had its  power supply removed 
and  was  used with a deaf telecom  modem......  however that large  
Michigan stash  has a   loose selenium   rect. power supply... loose in it.. could 
it be  that  the 19 might have used this!?  Perhaps  just a later issue  of 
a 19  with a later  powersupply?
 
  we need the clock  face  lie  position indicator  of  anyone has an extra.
 
On the plus  side  we  added a  model   14  shelf that  goes over the  TD 
to park a typing reperf  on   and we  got a aux large   copy  holder.

When I  got my model 19 earlier this year it came complete with the 
gigantic REC30  rectifier box. It uses a pair of 323B thyratrons to 
rectify and regulate  DC for the local loop and the punch magnet. 
One of the thyratrons was bad  so I made a substitute power supply
to operate it. After a number of  attempts I managed to get a pair
of working NOS 323Bs and let them cook for  a while, and now the 
full light show is now in force with the thyratrons  and neon lamp
