..Just got to find out if I can retap it to run on 240v and not 208v

If ya want, I've got a couple of 240V > 208V buckie-bricks, just sittin on the shelf, collecting dust... we use 'em for the Purelights, so.. I'm sure they'll 'handle the amerage'...

PM-me if ya wanna chat-further...

PS - I'm envious... (..yes, I know, 'wierd' as that-is.. I am..

Lookin forward to yer pix, Dude..

643 no need retap.

Switcher...

Don't slide the cathode tapswitch. Its NOT ment to be slidden, unless there is a serious cathode inbalance. (new word, slidden...) A one time only cloud of Sparks can happen.

The 543-643 psus are well covered in the FAQ. Unless you have the 170 varient, its basically a 150R with two extra added parallel fets for a total of four. The transformers/slideswitch are then set for 220 and the noise gain potentiometer adjusted for smooth operation on 220.

The 643 tube voltage is just a little too high to run off 110 VAC, so the 220 mod is invoked.

Well it trys to start.. I got a wink of red out of it lastnight. So theres still life in there... But it seems like the starter is weak..? Could that be why its lighting down the return?

[djmatt]

It lives!!!!!!!!
After many hours on the phone with Evergreen and Melles Griot and Mixedgas... I figured out that the PSU was the prob. Its max current is 9.3 amps it was pumping out 15+amps!! So after taking the other blown PSU apart I rebuilt it and everything works but the POT on the front..but the pot inside the PSU works
Its got 4 lines of blue a hint of green ( its got kill green optics) yellow and red! Not sure the power, but its beautiful!!!!
posting pics in a sec.!

Here is some pics of the PSU and the laser running!!

This looks awesome Matt! I would give my left nut for that sexy beam in solid state!

That's awesome, Matt! Glad to see you got it working. Man, are ION's making a come back? I'm thinking solid state projectors might be taking a back seat at SELEM this years, which happens to be in 7 months!

If I had some extra cash I would get it too!!!
I got mine for $440
I bought mine with out seeing it lase, so to see pics of that one working is a plus!
Keep in mind they don't have alot of power,but they are beautiful!! The most I've gotten out of mine is 81mw at 7 lines,but I still haven't had it to max currentand I never will!!

Sweet! Thanks, Jon. Another proud new member of the PLIOC!

[mixedgas]

That tube looks good enough to be a candidate for the "Glue the Supermagnets Round the Bore Trick"

Would you mind sticking the all lines OC in?

[djmatt]

Im working on it right now

[djmatt]

Well it turns out that its yellow blue only....

[Vidal Wolf]

Im curiious to see that color combo & what the beam thru a prism or grating looks like. Would you be willing to take a couple pictures? Im trying to imagine it..
Thanks.

[djmatt]

Which one? The blue and yellow?

[Vidal Wolf]

Which one? The blue and yellow?

Yup, the blue n yellow ones. If they're still mounted.

[djmatt]

Sure I can do that!

Very nice Matt, makes me look at revisiting my ILT krypton. Do you still have that extra set of optics that would work with it?

[djmatt]
