Re: Amp flyback install issue.

Well so far so good. Replaced the HVT, and was able to mount the MCI in one
of the existing holes, and drilled a second hole mount the MCI to where it
just fit inside the HV cage with just a small wire bridge. Replaced the two
HV caps with some 220uf, and I now have HV. My next problem was the Anode
wire coming out the top of the HVT. Couldn't bend the wire enough to mount
the cage, so I had to drill a hole in the top for the wire to come out.

The next problem is it looks like someone modified the colors so that it
would emulate a BW monitor. Plus I have no Z, so I have retrace lines. :(
But I'm making progress.
