Re: reversing polarity of a Glassman model LT from P to negative

maybe looking at my schematic for the current sense in the two polarity options and how the jumpers are configured between polarities, might give you some clues in hacking your device Yes, that might help. The 2000 Watt LT has a HV section polyethylene or polypropylene white box to full width of 19...

Re: reversing polarity of a Glassman model LT from P to negative

It is all guess work, about how to finish the conversion, unless someone can provide informed information about this design of multiplier. Yes, I was hoping to find someone with schematics, since the company now refuses to divulge old schematics. Glassman HV was bought out is why they refuse. Next ...

Re: reversing polarity of a Glassman model LT from P to negative

I have other Glassman HV section info that may be similar if you are able to hack your circuits. Yes, similar models would be helpful in figuring out the metering jumpers. Hope you kept their blobby soldering style Yes, I preserved that when I reversed the diodes. I used the opportunity while rever...

reversing polarity of a Glassman model LT from P to negative

I've got my diodes flipped, but am not sure about the jumpers of the HV module to flip the metering... and the manufacturer is no help: "I’m sorry but the model you mentioned is one we manufacture for an OEM Customer and due to our agreement with that customer, we cannot provide documentation, repai...

Glassman WX schematic and input voltage mods

glassman-WX-AD.png I got helpful schematics for the WX series of suuplies from Glassman HV. When I mentioned the supply would be used for fusors he suggested to do the modificatioin for faster response when driving a plasma,"Given the plasma application, there is an easy modification you should do ...
