The picture it produces now is pretty good for it's age, just some slight ringing seen in it, not TOO bad, if I wanted it any better at this point, I'd have to make up a video amp and boost the composite input to 5v P2P, and right now, it's not really worth it.
All that remains to be done now is to replace the asbestos DEATH sheet heat shield that was above the AMP/Radio unit, that thing puts out a HECK of a lot of heat, perhaps add a fan to it, add a secondary grounding wire between all the chassis units, and add a master power strip, I don't like how it was all originally daisy chained.

On most of the radios I've worked on that had a sheet of asbestos in the cabinet as a heat shield, I usually just leave it be if its still in good shape (which is usually the case 95% of the time on the radios I've worked on) because they say that as long as the asbestos isn't disturbed or flaking then you're ok to leave it in place, otherwise if its been disturbed, damaged or otherwise compromised then that's when you have to remove it.
As for disposal I don't know what the rules are for where you live, but where I live usually you just take the asbestos put it into a plastic bag and seal it up like you would any other garbage bag and then throw it in the trash dumpster, or take it to your local sanitary landfill to dispose of it.
Anyways I'm glad you got it up and running.
