Klipsch KSW10 transformer

I need a replacement power transformer for this unit. The numbers on the
transformer are 042-010078-000. Underneath this is ELY 0241. It also has
a sticker marked H.P. Two blue input wires, center tapped outputs, outer
two yellow, inner one white. Outputs measure 1.5 ohms to center, both
sides, and 3.0 ohms outer. Input side is open. Can anyone recommend a
source? Klipsch will not talk to me, as I'm not an authorized repair
center, just a home guy fixing his own stuff. It was given to me free,
and I'd like to fix it. It doesn't appear to be cooked, as the lacquer
is not burnt, and no burnt smell.

The only source for Klipsch parts is from them. They have a technical
support service. I don't know their policy, if you will have to send the
unit to them, or they may sell you the part directly.

Apparently the primary winding has opened up. This is a bit strange for
a quality product like Klipsch. Time to investigate and see if it's
something simple, like a disconnected wire.

Remove it from wherever it's mounted (if you haven't already) and examine
it. Figure out how it was assembled and start dis-assembling it,
particularly the primary winding.

Can you find a break in the connections to the primary winding? Has a
wire come loose from a terminal? If so, solder it back together.

Can you unwind the primary winding? If it's easy to unwind it, do it!
Count the turns as you unwind them, measure the length of the wire, and
figure out what size wire is used. Buy some new wire and re-wind the
primary.

If the secondary winding interferes with unwinding the primary, consider
unwinding the secondary first.

Transformer is useless as it is, so why not have a learning experience
with it?

Man, that's a change from when Paul was running things. I once blew out
the 15" woofer in a K-horn -- my fault (a transistor shorted in the
amplifier, which was my own design). I wrote Klipsch, asking about the
cost of a replacement. Paul sent me a new one along with a note saying
"The woofers in Klipschorns should not fail".

The most likely place for a transformer winding to fail is where the
winding wire connects to the external leads. You might try *gently*
removing layers of paper from the thing to expose the joints. you may be
able to find the break.

generally there is no need to get power transformers from the original
mfr, as theyre normally generic items. You'd need to know voltage and
power / VA specs to get a replacement.

Rewinding works but is a hell of a job, not something I'd ever consider
today. Once was quite enough.

I used to get fan motors rewound for $6.75 each. Man, I am old.

Some transformers use to have a fuse embedded in the primary winding.
This was usually visible as a big lump near the outside of the winding.
If you can't get a response from Klipsch try talking to an authorized
repair center/dealer. Some won't want to talk to you either or want you
to bring the unit in, but you might find one who would sell you a
replacement OR look at the schematic and tell you what the secondary
voltage is so you could get a generic replacement. Good luck
