where to get NO diode embedded flybacks?
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. AB |

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.

None of which have diodes installed. 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. 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: https://www.rockauto.com/en/catalog/...,focus,2.0l+l4 +dohc,1431898,ignition,ignition+coil,7060 |

AB 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. |
