Preliminary Testing Shows Deflection PCB Works Great

A project log for BUILD an ARCADE XY VECTOR MONITOR

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

Okay so I have the deflection PCB all assembled and broke out the space duel pcb that I bought on ebay as working only to find it was resetting and not working.. DOH.  So I broke out the Asteroids PCB I bought on ebay as non working.. It works 90% so good enough for now. I will repair these pcb's when I get a chance. I really wanted to test out the deflection. The china 24V power supplies came in and they seem to power everything just fine.  As you can see from the pictures I have a display on a 9" TV. The deflection is working perfectly. There is no control of any of the CRT guns so you see all the lines drawn on the display.  Even though it appears to look bad right now this is a major step forward. I now need to design a high voltage circuit. I think I am going to use a reproduction wells gardner 6100 flyback. So thats on hold until I can get a few bucks to buy one. I also need to design or redesign the CRT gun driver.

On the TV CRT. Notice I took the picture upside down as the yoke needs the wires swapped .  Just wanted to get a picture on it tonight and make sure the deflection was working so I can move on to the High Voltage.
