Who bought the 4 Plitron 18x4 V 1.5kva surplus transformer?

Anyone here bought them??
I've had an eye on those for a while I went to buy them yesterday and found they were gone.
Do you need them all??

Hi Grataku,

I called Plitron in early to mid December and was told
then that they were already gone.

Just out of curiosity, do you really mean 18 x 4V, not 4 x 18V?

Surplus transformers can have very strange secondaries that
makes one wonder what on earth they were intended for.
For instance, a surplus company in sweden sells 1,3kVA
transformers with 3.15V 13A plus 2300V (yes, 2.3kV) 0.7A.
Nothing I have any need for, but it makes me wonder what
kind of application could make use of that combination at all?

I'd be willing to be it had tubes in it. Maybe a radar power supply?

Yes, it was 4 secondaries of 18V each. Would have been perfect for aleph2 by putting the secs in series, or for alephX. My guess is that Peter bought them.

I would guess on a more common item than haldor suggested: Microwave oven :-)

BTW, which surplus company was it?

Well, a very low voltage and a very high voltage immediately
tells me it's probably for valves, but here the low voltage
seemed too low and the high voltage too high. I suppose
special things like radar or maybe more ordinary radio
transmitters might have higher voltages than usual valves.
As for microwave ovens, I wouldn't know. Was that a joke or
do we have such high voltages in our micors??

No, there actually is very high voltage inside microwave ovens. Look at http://www.repairfaq.org/sam/micfaq.htm#micsaf
