The Dokert/Chris25810 Busted GO7 Challenge/Donation Contest
Several weeks ago, Dave aquired a frickin mangled GO7-CBO chassis that he started a thread on and jokingly offered it up to me to see if i could do something with it. I took him up on the challenge and told him that if i could repair it and feel comfortable that the repair would hold, i'd donate it to someone here that really needs one. This was definitely the most amount of breaks i've ever repaired on one of these things and honestly, it looked much worse on the bench than it did in his pictures.
Every flyback trace was broke, and the upper right corner had two other large breaks. There were several broken small traces in the deflection area and of course it was cracked on the video side just in front of the frame. It took a shitload of solder, cap legs, a few wires and some epoxy but this thing has been running on my rig for several hours and it has a rock solid picture with a perfect B+
The other issue at hand was the previous rebuild on this mess. The rebuild work was mediocre at best, (sorry if i offend somebody here but it was quite shitty) the anode clip was ripped off the flyback, you needed a microscope to see the solder on the replaced caps, the insulator boots on the focus tower are all ripped and somebody figured wads of electrical tape would be a great repair. I normally wouldn't fix a chassis like this as it's hard to know how people are gonna handle it on an install basis and it's hard to know if the repair will even hold. The only reason i tried it was because it has alot of new parts already and i was bored with the typical chassis repair thing.
This is being donated to somebody here that really needs it. We're not quite sure how to go about chosing the needy one but my initial rule is that you have never bought or had one of these repaired by myself or Dave.
This chassis comes with:
A fairly new flyback
Newer caps (including filter cap and bi polars)
New width coil
New R908
New F901 fuse
A little bit of grime, alot of epoxy, cap leg bridges and plenty of added solder.
