looking for power transformer - no search results

have a Technics Graphic Equalizer, power transformer physically broken
out of case due to a big thump/drop.

OK, 3 numbers stamped on the side, figured one or all of them would
turn up in a Google search - nothing, zippo, zilch. Tried segments of
each, nohing resembling part numbers for a power transformer.

Any help would be appreciated, even if somebody points me to which of
the 3 is the best choice, as in the real "universal" part number, the
one I should be searching for. Here they are -

P48U20*D (the * is a delta symbol)
SLTK5K6
ETP48KL4A

Also has 653A on there, but disjoined from the other 3 numbers.

Thanks in advance.
(If not too much trouble, also please reply to e-mail.)

There is no standard numbering for transformers.

I expect that power transformers in mass-produced equipment are
custom-made for the particular application.

You will probably have to get a replacement from Technics.

Can you not wire it up and see what voltages it outputs?

Clik on catalog and search for the part number - 18 bucks, but not in
stock.
I looked at the catalog for unijunction transistors. They also were not in

stock and seemed to command extremely high prices compared to Fry's.

Look at the power supply board. You should be able to determine the
secondary voltages required for function.

Most analog graphic equalizers simply require -/+ op amp supplies.
Digital versions will require the additional digital rails.

Unfortunately, the jolt not only broke the plastic mounting frame, but
it also ripped the wires right out of the pins. It's a mess

It's an older piece of gear, but a good one. I'm trying to see if
there is a quick fix (buy/replace xformer) rather than a long journey
through OEM schematic, parts list, etc. Purely economics. X hours of
my time taken up = just pitch it and buy a new one.

If it is solid state, probably no easy way. However if the power supply only
puts out one voltage (center tapped?), you could hook it to a DC power
supply and slowly increase the voltage until it works. Compare that with the
voltage rating of the filter caps and see if you are close. That should get
you close to the transformer voltage needed - shop around and see what you
can find.
