Looking for a source for getting NO diode embedded flybacks to be able
to run multiplier circuits, etc. I am in the US. Thank you.

Would be useful to know desired operating voltages and so forth, but Mouser has a selection of low-voltage PCB mounted devices.
Triad has a number of higher-voltage devices.

None of which have diodes installed.

Google is your friend.

LCD TVs don't need flybacks!

Something like this?

Couldn't even buy the wire for that price...

Sorry, I was looking for something in the 20- 40 KV range like was found
in CRT's. Probably 15-20 KV at some mA since I was going to use a 3-4
stage multiplier.

Who said anything about?--nevermind...

LCDs with CCFL backlights, though. Low power (10s W), high voltage capable
(3, maybe 5kV peak?). Comes with resonant driver circuit, full wave, not
flyback.

Look for a 4-cylinder wasted spark ignition coil. It has two independent
high voltage flyback transformers. You can probably put them in series for
higher output voltage.

They are inexpensive and available at most auto supply houses. For example,
the ignition coil for a 2003 Ford Focus starts at $16.75 at Rock Auto:

Ebay seems to have the AC ones, but take a good close look at the
condition before purchase. You can sometimes google the part numbers of
the advertised device and come across a TV manual showing KV output of
the transformer if that's important.
