Ralph,

Can I ask for a clarification on what you mean by power supply on those
partial
modulators.  Since these are powered via an external DC supply (AC for
filaments) none
of them really have a power supply on board.  However, they do contain one
metal can
electrolytic cap and a modulation transformer.  I think the one I bought
from you was
one of the $95 versions as mine did not have the electrolytic and modulation
transformer.

If the above is the case guys, I'd recommend paying the extra for the $150
unit as it
would have the modulation transformer.  The transformer was a special build
for this
transmitter and you won't find an exact replacement anywhere.  However, you
could do
what I did with mine.  I found a NOS electrolytic no problem from my junk
box and I
think they should be available elsewhere.  For the modulation transformer I
used one
from a Johnson Ranger that was currently not being used.  A special thanks
is due here
to JMS member Roger W9UVV for providing a replacement Ranger iron so I can
eventually
get that transmitter operational again.  The Ranger iron works wonderfully
in the
90831 modulator and even it's two mounting holes line up perfectly with two
of the
four original mounting holes.  No new holes!

Roger already indicated the #113 sold.  Not unexpected.  That's the last NOS
modulator
in the world!!
