Default What Do I Have Here?

There really should be a special forum dedicated to identification of tubes and stuff we find in our attics or garage sales etc.

In any case picked up a Lambda c-882m tube power supply.. for no peticular reason except it was in such good shape and i thought i might want to use the case for a project.

In any case I at the point where I need to decide.

a. Do I invest in the dozen 6l6GC tubes it needs to operate
OR
b. Strip it out.. sell off most of the parts and keep the case for another project.

What do you think?

Other questions I have.
1. where do i plug it in? i cannot find a cord or a place for one.

2. are these giant caps any good? paper in oil? or would they need to be replaced for it to work?

3. would something like this only be useful for testing purposes or could it serve as a good supply for an amp?

Any experiences with massive tube supplies like this.

Oh and it weighs about 90lbs. insane.

What would you do with it?

Few things..
500V 500Ma supply is a good item, but looks like it needs
alot of work and money to invest..
6L6's can add up
12AX7 and 5Y3's too
Also looks like you need to replace all the fuseholders.

Input shows on the terminal board bottom 115V
Output above with NO senseing jumpers needed.

So, bottom line, If you need one Lambda is a great name
and great for tube work. I would sell one like this if
I had one in stock for $250.00

Forgot one thing: The caps do not say NO PCB's and
will be concidered hazerous waste

My 2 cents

Looks like a good supply. I'd fix it up and use it, but that is me. I'd get some old Russian 6P3S, I think that is the number. Its the equivalent of 6L6's. They are super expensive, so you could retube for less. Get it off ebay and you can likely get some 12ax7's and the recitifier from the same dude.

I think the big square things next to the caps that say AAN____ are the transformers.

Take care of the fuses and safety issues.

Those capacitors are foil and kraft paper in oil. Very little chance of any problems with them if they are not leaking. I have the little brother of this Lambda supply. Lower voltage and current and uses six 6W6 pass tubes to your twelve 6L6's.

IMO it would be a huge sin to part this out. Someone needs a fully regulated vacuum tube bench supply like this and will pay the bucks if you don't want it. That should have no problem commanding $500 on epay if you can find someone who has not been hurt by the global recession.

If you need the room I'll store it for you on my lab bench.

Heyyyy, I have the lower voltage version of that guy

Most lovely bench supply I ever had. Not the best, but the one I love the most


I worked on the portable version of yours for Planet10 and his used 6 x 6W6, not 6L6

Cheers!

This reminds me of the tubed psu i got, only mine was fully stocked and ready to use.

IŽd say, get this psu back in working order, they come in real handy sometimes when working with tubes.
