Ok, I am working on getting all my boards going for both of these Gorgars I got last week, I am almost
there, one slight glitch I can't figure out, First let me state I have a perfectly working Gorgar which I am using as a Test Host. My Drive board had a blown Q15 ( kick out hole) I replaced the it with a TIP 102 and also replaced the pre driver. It booted and played then after 5 mins blew again. replace the 102 again and replaced IC1 (7408) Still no luck, still blowing. So now I am thinking IC 5 (PIA) Am I heading in the right direction?? Popped my original drive board in and all is well, I think I am quitting for tonight!!

I went to check the diode on the coil and saw a slight burn under it on the coil base. Probed it with my
fingers and it broke in half, seems it is probably the culprit!! Can't figure out why it would run fine on one board and not the other? I'll change it out and see what happens, a lot easier than doing that PIA because it's a big PIA, pun intended! I don't have a probe, I am thinking it might be a good investment though, if I can figure out what I am doing with it.
Thanks guys

Well turns out it was the diode on the coil, replaced it and put a new TIP 102 in and all is well. It's been playing great. for 1/2 hr straight. I now have 2 full working sets of boards!! I am still puzzled how this pin played with it's original drive board and did not blow the same transistor, must just be a more robust board. I Also noted I got more ghosting on my LEDS with the different drive board, Interesting.
I am sure learning a lot getting all these boards up and running, I'm finding it is more fun fixing than playing lately, is that strange or what.
Thanks for all the help
