yes, it is unsafe to use at this time.

My cord comes out of the head and runs thru a transformer.  I now have
gather enough information to think this might have been a custom Bessler,
for the following reasons:  It has a special swivel bracket which I thought
was just for shooting onto a wall mounted farm for really big enlargements,
which I have done with it, but a person that is considered one of the best
black and white zone system printers around says that bracket is a
customized job and so is the 4x5 extension cone I have.  So the power supply
to the head might also be customized: Which means I will have to go back to
the people I had fix it after the soaking it got and eat a little crow in
front of them as I say I am sorry for calling him a malodorous, braggart,
that doesn't know s&$% about fixing equipment.

I hate it when that happens and the older I get the more I have to do that.

And to the little lady who ask how much I paid for it at a pawn shop:  For
the Bessler 23C II with all the extensions and frames ;three tool boxes full
of extra's (most of which I have no idea even now what they are) ;the 3 sets
of trays; a roller washer; 4X6 wash sink, with temp control; bulk film
rollers; about 27 books on the zone system and printing; two paper safes; a
really cool safe light with exchanger vent:  I paid $2250 plus tax.  And the
filters that came in one of the tool boxes are considered to be some of the
very best German made filters and are no longer made:  I have been offered
$200.00 for and found same on E-bay for much more than $200.00.
You are correct young lady I got a great deal as the Pawn Shop was moving
and didn't want to move it all.  So I think it might be worth your while to
check the pawn shops out, just make sure they have at least a 30 days return
for cash in case you get it home and it doesn't work.

Let me know
