MAC SE/30 with orange colored CRT

[nickpunt]

I messed with the centering rings and improved the picture, but there's still larger geometric distortion on the top and bottom right. I'm looking at maccaps guide and tried to rotate them a bit with needle nose pliers but they were hard to move and adjusted things in unexpected ways since they didn't rotate cleanly - you let off the pliers and the picture looks different than when rotating. I could only safely access four of them. Would love to learn more about how to do this, what tool to use, and which ones to adjust for what problems. I'll take a look at that service manual.



The flying toasters in amber are a pretty fun effect:

The flyback has 7 pins, 6 of which are connected to wires. The label itself has 1745 printed on the side, then on the label 95-3574-05 probably as a part number, and below that EIA 343 4 and Made in Taiwan. The cable coming from it is made by Sumitomo, so perhaps that is the manufacturer of the whole thing.

A while ago I swapped the CRT in one of my SEs with a amber one(from a piece of medial equipment of some sort) to move the original CRT to my SE/30 with screen burn in, and it had the same issue with the anode being on the wrong side/the pins being upside down.  I ended up just extending the cables that go to the board at the end of the tube, so I could keep the anode cap on the right side of the Mac for easier discharging

General question: should the neck tube have a glow like a guitar amp's preamp/power tubes do? 

I left it on only long enough to boot to the Finder. There's an audible "pop" when I turn it on with an accasional accompanying (dim) flash from the tube, then as the computer boots, the glow steadily comes back on. This is with that green Matsushita CRT.

@techknight Bolle suggested I tag you and get your thoughts on this. On IRC he said:

The heater voltage is coming right from the V supply which is coming right out of the flyback, so I'd say you could kill your flyback if something with the heater is wrong or not in spec with what the circuit was designed for. But let's see what techknight says, he is the man with tubes and all that stuff
