After a long wait, and paying unexpectedly high fees to the freight
clearance company I finally have my hands on my 029 keypunch. To my
surprise it has an extra wide punching station which apparently is an
extra read head which allows it to be fed with ready-punched cards and
the text to be printed at the top of the card. An interesting bonus.
It uses the same wire relays which have been discussed here recently,
and fortunately I have a 303 ammunition box full of spares including
many of these from a verifier I broke up some years ago which I kept
for my 836 punch.
The rating plate shows .4kVA which is more than my Flexowriter
transformer can handle so I have ordered a modern yellow industrial
110v socket so I can try it on a 3kVA transformer I have for an angle
grinder. I have searched though eBay for normal US wall sockets and to
my surprise cannot find them. I've tried all sorts of search terms but
obviously have not hit the right combination, unless there is some law
which prohibits them being sold retail or something like that.
Probably me being stupid.
Looking through the parts list there is something I'd like the list's
opinion on. The diagram shows a transformer but the list says
"REGULATOR ASM, FERRORESONANT-60CPS 120VA" and a similar option for
50Hz which of course I don't have. What are these for? Might they work
at the wrong frequency? Will they be damaged or just not work? This is
part of a 48v DC supply. Should I build a simple 48V supply myself or
even see what I can find in my verifier spares?
