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

John G, So from what you said last, I think your supply has a white plastic box around these boards too? If so, could you share a pic of that -- just to improve my knowledge of what's out there. Lot's of Glassman stuff seems to share common design configurations. I'll share some info on a HV multipl...

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

John F, Yes, the white plastic box is the HV multiplier section. Swapping it is the usual way to switch between P and N polarities. The ones that were shipped with two multiplier sections have an R in their part number where P or N is in the normal single polarity versions. A P multiplier can be con...

Re: HEAS Conference photo album for sale

I understand now.

Just from the poster's name, I should have been able to extrapolate why the price.

Thanks for the clarifications, and thanks for putting forth the effort to create this.

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

John, Thanks for the pics. I haven't seen a Glassman HV multiplier section that looks very much like that before. Main thing that I'm looking at is your 3rd pic (top view). Although new to me, the general scheme seems to make sense. The lower right quadrant looks to be the multiplier section. I assu...

Re: HEAS Conference photo album for sale

Wow, that's pretty steep pricewise. Is it a profit goal or is there some intrinsic cost I'm not seeing? I'm a Vietnam vet and just finished updating a DVD we did years ago. Filled with video one guy recorded. Price per DVD on the latest batch ~ $2 ea to make on my late timeline. To share, we could g...

Re: HEAS 2019 photos of the event

On vids... Not the way we like it for long term preservation but.

How about opening an account on youTube or Vimeo and sharing the links?

Re: FUSOR.NET v4 is now LIVE!

Frank, Hope you are monitoring. Here's another issue since the move. Back around this time of year in 2017 we exchanged some emails about the screen that people see when they first click on 'Register'. They have to agree but the default phpBB screen is typical boilerplate -- blah-blah-blah, TLDR. We...

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

PS

That's a lot of work to reverse all the multiplier diodes. Hope you kept their blobby soldering style. All that excess solder is there to make a rounded shape to reduce any sharp peaks that could induce HV arcs.

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

I have accumulated some Glassman info. Not on the LT but it could be similar to others. Got a pic of your LT multiplier section? Overall, and a pic of connections might help populate the knowledge. I have found the basic instruction manual as a pdf. No schematics and not this level of detail, but I ...
