Compact Flyback Transformers

I hope someone will find it useful to know that Dalbani.com still has four compact Mac flybacks in stock for $8 each, but they have a minimum order of $20.

The part number is a little odd, 157-0026V, but I ordered a couple of them and they look just like the 157-0042B flybacks I have on hand. I don't know if these have an internal bleeder resistor or not. And I don't actually know for certain that they'll work, but it's hard to imagine how they could have that part number and that form factor and not be made for the 9" B&W screen (also used in security monitors).

The two I received were rather dirty and even had a few slightly bent pins, leading me to wonder if they were used, but I saw no signs of prior soldering. I think they've just been in storage, perhaps on an open shelf or box, for a really, really long time.

They also have the BU-406 transistor available.

 
I have seen a 157-0026 flyback on a Mac Classic II Analog board I recently recapped.

It looks identical to the 157-0042C.
