Hi,



To those who own the Saunders/LPL enlarger -- and -- to the great electrical
engineers of the world who happen to be photographers.



I own a Saunders/LPL 4500II 4x5 enlarger from before OmegaSatter took over
the line.



I just purchased a new power supply from

B&H.



Note that the picture on the website is not accurate - the power supply being
shipped is different - OmegaSatter is now shipping the original power
supply developed by LPL (part #200400).  Unfortunately the new power supply
is not compatible with my old power supply. The 4-prong connection on the cable
that runs from the enlarger to the power supply doesn't fit!



I talked to Customer Service at OmegaSatter and they said that "Saunders
bastardized the enlarger by developing a different power supply than designed by
LPL." She told me that Hazlow Electronics in N.Y. (585-325-5323) developed the
Saunders version of the power supply.  She also said that they have had
customer complaints about the new power supply not fitting the old-style
connection to the enlarger, but do not have a solution. In other words, I
am SOL.



So now my questions:



I write software for a living and know little about electronics, but I am
hoping I can use the new power supply.



I called and left a message for Larry at Hazlow Electronics and hope he will
be able to help. But failing that, I am hoping someone here can help.



Does anyone have a schematic for the old power supply? The cable that plugs
into the power supply has 4-pins: but I don't know which pins are for what
(options are: fan, lamp, ground).



The new power supply schematic states the following (formatting below is what
they show):

<ul>
<li dir="ltr">
<p dir="ltr">No.1-2pins to Lamp.</li>
<li dir="ltr">
<p dir="ltr">No.3-2pins to Fan.</li>
<li dir="ltr">
<p dir="ltr">No.4-to Earth.</li>
</ul>
<p dir="ltr">So I take this strange formatting to mean that Pin #2 is doing
double-duty. It is serving both the Lamp & Fan, and that Pin #4 is ground.



Does anyone know where I can buy the 4-prong connector for the new power
supply?&nbsp; (This assumes you know what it looks like -- I don't have a
picture of it, but it is a round connection with 4 inputs.&nbsp; How is that for
a description?)



Could there be such a thing as an electrical adapter that would fit the old
connector & the new connector? (This assumes you know what the old connector &
new connector look like.&nbsp; Do I need to do a Google search?)



Has anyone else come across this problem? Do you have a solution?



I bought the power supply as a backup because of the great price ($160 vs
$360 or whatever other places are selling it for).&nbsp; Fortunately my old
power supply still works! But I'd like to know if I can get the new power supply
to work with my enlarger, otherwise I'll return it to B&H.



Thanks,



Justin
