Custom Plitron tranformer for output stage
 
I was thinking of getting a good power transformer unit to use for my future power amp project.
Since i have noticed that the 18+18V output secondary is the most wide used from NP and that he ONLY uses Plitrons which are very excellent manufactures, i was thinking of buying 2 customs made

specifications:
-----------------
1.5KVA
low noise and low inrush
mu-metal shielding.

since such a transformer is not available on the standard range it has to be custom made and therefore there is a fee of $250 for the first one.

If anybody here would be interested on getting such a good product with me, we could share the fee and by requesting more units the price per unit would be even lower.


i thought it could have been a nice idea since we are not obviously Nelson Pass that can order loootttsss of units and get a good deal :D

If anybody out there is interested please let me know.

Now all that's left, is to find something to use a 1.5kVA transformer for :rolleyes:

com'on Magura, i am sure you have plenty of imagination to figure out on your own what you can do with that, can't you? ;):cool:

Stefanoo 4th June 2008 05:43 PM

Then if you are not interested why are even posting here?
I don't understand!

It appears to me that your only reason to post is to be sarcastic and/or start an argument and i am sorry but i am not willing to, absolutely not!

I could give you tons of example of how you could use a 18+18V power transformer but i am not going to.
If i misunderstood your intention then i give you my apologies otherwise, please just stop to reply.

Best

Alternatively you can come to Burning Amp this year. Last year
I was giving away Plitrons that roughly fit that description.

Toward the end, there were still some left, because a lot of
people came on bicycle or took the bus.

BTW, I saw and handled those 1.5Kva transformers. These things are massively large and heavy. I could not imagine mounting them in a DIY system at my place.

Many of the BurningAmp participants had a lot of jokes about boat anchors, bridge abutments, ballast, and wrecking balls to describe the size and weight.

Yeah, i know they are heavy piece of equipment....but i don't understand why you wouldn't install these on your diy amplifiers (if the reason is the expense then....i agree with you).

Nelson: you meant that some of those transformers you bought from plitron don't fit the requirements of low noise and low inrush and therefore you give them away? or you are giving the surplus you have away?
If so...i wouldn't mind to buy a couple of them :)

Hi Stefanoo,

Just wait until you actually see the size and weight of these things. It's impressive. With heatsinks and refinforced chassis to support the weight, the amp would need a hand truck to move it around the listening room.

But I still managed to carry two 1.5KV transformers home using the city bus. Many breaks required.

Some are older types, some don't pass the stethoscope test.
