Time for a much needed update. High Voltage coming together.


I set out to build a working 13"-27" CRT Arcade XY Vector Monitor. UPDATE!!! 5" and 9" monitors too.

Okay I have settled on a elegant and cheap solution to making the High Voltage.

If you want to follow a long you will need to buy one each of these items.

2SD2599 or equivalent Hot transistor. Most of the newer hot transistors will work. (I used one out of a 13" TV)

One of these SMPS.

This flyback is the one I settled on because it is cheap and available.

555 timer, A few fast switching diodes (UF4007), 2n2222, some resistors, capacitors and misc. Most stuff any good parts bin will have.

Some of you might ask why did you not use a WG6100 or Amplifone flyback. The answer is simply because it was cheaper to use the above components. The WG and Amplifone flybacks are $40 or so each (I even asked about price breaks). All the parts to build the version I made should be less than that to build with all new parts. I was thinking about designing a pcb with a SMPS for B+ when I found that the Chinese already built one for less than $10.

Stay tuned for lots of updates and in the mean time collect up some parts.

looks good. Just have to adjust for the different pin out.

Would this one work?

  Are you sure? yes | no

What characteristics am I looking for in the flyback? Unfortunately from here the shipping on that particular item costs more than the parts.
