thanks  for  the input Rob!
 
What is scary is how small this  5 is  for the claimed output  power... 
what is even scarier is how  tight everything is  packed in  it!
 
The  nice one was  very low $  or  free... the   rough one  was definitely  
free...   and even if  I do  not  fire itup... it  is a example with  some 
of the other   things  of the  era  in the  display...
 
We also have a SB-101  Heath we need to get  going  but I  assume we  will 
need to throttle the output  back on that   too.

No.   That's a low duty cycle rig, one of the wave of lightweight low
duty cycle  rigs that came out in the 1960s to make SSB affordable.
You probably have  to be careful even just tuning it up.

If you want to run RTTY with a  vintage rig which is admirable,
especially if mechanical equipment is being  used, and I'm assuming you
are going to FSK the rig, the real RTTY way to  do it, you need a high
power CW rig, or a RF amplifier built for AM.   That means an early
Hallicrafters amp for example, or the Heathkit Warrior  or Chippewa.
Or something homebrewed.

Lift up a Warrior and you'll  know right away.  It weighs twice maybe 3
times as much as the wimpy  desktop amps sold 15 years later, the Drake
L4 perhaps being one  exception.

It's the power supply which I think is a choke input, what  you want
for continuous duty and a non-dynamic load, plus a plate supply  that
can provide the plate current at power continuously.   Those  amps
aren't sky high Peee Eeeee Peeee, a meaningless power  specification
for suckers, but put in four 572Bs and it will sit there and  put out
500 watts forever.  This is why RTTY ops seek them  out.
