does anyone know how i can make my own transformer since we can not find one all ready made anywhere. and where i can find those capacitors on that schematic cause i can only find the polarity sensitive one in the bottom center o the board.

does anyone know where i can get a transformer like that or maybe how i can make my own.

does anyone know where i might be able to find a transformer like that. The interference really will not make a difference because the guy that i am building it for lives in Ukraine and his closest neighbor is 10 miles away from him so it will be fine.

the diagram says that the battery is supposed to be 12volts for the power source and since i realize that most of you can not read Ukraine the side notes in the top right say that L1 and L2 are 1.5mm devices rated at 17 each and L3 is a.3mm device rated at 700. which is why i could not figure...

one last question, just wondering what would L1, L2, and L3 be is it just coils of some sort or would it be a a step up transformer.

the resistance should stay below 6 amps since the original power source has only 10 amps. I might try both options and see how it works out if anyone has any other ideas or better solutions let me know. Thanks for all your help.

If I did try to use the MOSFET idea does it still get hooked up the same way as the transistors do. Would they have 1 on Mouser.com since that is where I get all of my electrical components. I am not all that great with electronics but so if you guys can help me that would be great thanks.

the schematic is at least 50 years old from what i know because my grandfather got it when he worked at a nuclear power plant back in Ukraine, before we moved to America. If anyone knows where I can find a chart to find the equivalent let me know, mean while I will try to find one myself but...

here is the schematic. let me know if you guys have any ideas that might work in place of the transistors.

I will try to get the schematic scanned into the computer and uploaded as soon as I can. Thanks for all your help.

thanks for that website but i can figure out how to us it or where i can buy one of those transistors any ways

I got a electrical wiring diagram from my dads friend for a device that he wants me to build for him but the wiring diagram is from Ukraine and i can not seem to be able to find any of the transistors for the device, If anyone can help it would be great. The numbers are KT835, KT827, and a...
