CET Technology DC/DC converter for VF-Display

Are the 6V pins used? Do they feed separate circuits?

They look like they are used. There are tracks goning from these 3 towards the display, but they disappear under it... There are three separate track going from them. I was thinking it might be heater for the vacuum display cathode? I have never repaired a device with VF-Display before, so I am not sure of the circuit... Do you know any schematic example? It looks like old, already "fogotten" technology today ;-)

What I am looking for is the place I can get replacement, or - an idea on how to build similar circuit from discrete components or other chip from different manufacturer...

Go back to their site and get their phone number. Many of these companies no longer respond to emails unless they specificaly know the sender. They get too much Spam. When you call have your credit card handy to place the order (if the module is stillavailabe). Take care, it is now cheap to replace.

If you brave and its not potted, pry the convertor apart and see if you can trouble shoot it. If its already dead, you cannot hurt it anymore than it is.

I had one of these displays on a Delco radio once that had me going. Turned out the tiny glass extension where they suck the air broke off and let the vacuum out.

I might be inclined to try to cobble together a regular AC transformer type supply to keep this going.

has a couple of converters, one of which (CAT# DC-32, "2 for $1") is somewhat close, but it's either that or a new pH meter.

has some weird crap too (along with annoying Java pages) but you'll have to poke around there for a while.

It is potted, so no way to get inside :(

I will double check the display itself. And maybe replace the module from the good one to be sure.

They responded with delay that this is special module made for Thermo Orion and I have to contact them for the spare... I can only imagine how much it will be from there :-) But I will give it a try.
