Hello Turk 182,

They are Luxtrol D6000 models. Rated (apparently) to 50 amps at 120.

I'm glad there's some potential for them because I did rather bust up my hand pulling one of them out of the dimmer rack!

was this an old Strand Century dimmer?
i'm tempted to ask if your selling any of them but i'm afraid that shipping weight might make the whole idea unfeasable.well enjoy you luck dog !
have you worked out a wiring scheme for any of them

I don't know if this was part of a Strand Century system but I doubt it because I don't remember seeing any branding like that anywhere, not really part of my area of expertise though (the projection booth did have Altec/Century equipment in it, but from a different/earlier era).

I imagine shipping would be crushing (I'm guessing they are 40lbs a pop), am happy to look into it if you're interested in some. PM me if you want to follow up on that.

What would be helpful for me (and the thread) would be understanding what exactly it would take (e.g. what range/rating) to add a panel meter to monitor output voltage and current and what would be the best kind of "output receptacle" (like I said, I'm a noob.)

I get that output voltage should be a meter that runs from 0 to "some number" but I don't know if, given these apparently won't let you transform to a higher voltage, that 120V is "enough" or if, since I am interested in tube/valve equipment I should have a transformer in front of it and a higher voltage range on the metering end.

the metering is optional it's nice to include but not ultimately needed. panel meters for a 0 to 120 vac or 0 to150 vac and current meters to 50 amps can get without knowing just how many terminals you have on these (pic's would help) i expect a minimum of three(some can have many more which opens the possibility of higher input voltages as in 240v some can be even more complex if they where designed to be powered from a three phase feed) for the moment we'll assume you've got a three terminal type think of it like a big potentiometer one terminal would be the high side the other the low or common and the wiper the output your input voltage would go across the full winding your ouput would be wired as neutral to a common(one side of the full winding) the hot comes from the wiper.
as soon as i can replace my scanner i'll post some basic schematics along with a few options like meters and a homebrew current limiter in the mean time should you decide to experiment with these please be careful the poke you can get from these can be lethal!

Okay, finally back to this project (I do have the excuse of having a newborn in the mix). I don't have the ability to post pics right now, but there are 3 terminals, single phase rated at 120V 50/60 Hz 6000W max. The weight is about 46 or so lbs without any packaging material! I am selling a few on ebay to pay for shipping the rest of them out to me here in CA - (no link to avoid violating any rules about that stuff here). Shipping is pretty steep via things like UPS or even parcel post - I'm thinking about just putting them on a pallet and doing a partial truckload, actually.

When they finally get out here I'll be wiring up a testing bench with this, a little DC power supply converted from a old computer's power supply and a few other odds and ends (contemplating building a larger bridge rectifier just for fun).
