So while testing out a G07 on your just-installed test bench, just an FYI, you do not want to take the clip that connects the sync to the sync pin and smack it against the heatsink for the D1138s. Nope...you get vertical collapse and kill your test board. Just in case you didn't know.

*sigh* this is a lesson for me to not hurry when trying out new setups.

Yep. Make a two pin molex for the sync and connect it that way. you can move it to negative or positive depending on what you are testing, or to just the horizontal if you need to do that.

On my test bench, I wired up both the positive and negative, then installed a switch that I can use to switch between the two depending on what board I am testing...
 
That's pretty much the way its hooked up, except I use an alligator clip. The only reason it failed is because the new location for the test bench has it a few inches farther away than it was before in the old workshop, so there was a bit of tension on the wires. I was trying both negative and positve sync to see if I could get the picture to lock, and when I removed the clip, I had "butterfingers".

I'm hoping if I trace the sync wire back on the board I was using I can just replace that chip and be good to go. Currently it's not outputting anything at all. And the monitor, of course, has vertical collapse, and I don't have any new vertical transistors.
 
Well...test bench board is hosed unless I can find the video processing chip. It's a Capcom Bowl board, so I'm not terribly worried about it. That may not even be the issue, but without proper testing equipment I can't be 100% sure. One day I'll find one and swap it out. Until then, I'm using my Strata Golden Tee board to test.

The G07 had the fusible resistor blow, and not the D1168s. That's good news, I've got a parts chassis. Going to pick up some to have on-hand with my next parts order. It's just a standard wirewound resistor, correct? 68 Ohm, 2W?
