The flicker is gonna likely be aging capacitors on the analog board. Ideally you'd replace these. For the pincushion I believe there are magnets on the yoke that can be adjusted...

After a false start with dirty contacts on the ROM simm and resulting irregular vertical bars, the machine is working again. There are no more zipping sounds coming out of the speaker. Two problems remain: 1) There is slight pincushioning along the bottom of the CRT, about a third of the way in from the left. 2) The CRT produces a rather noticable and irritating flicker. I don't remember the one-piece Macs flickering like this. I think a cleverly-placed magnet might fix the pincushioning and recapping the analogue board would remedy the flicker. Can I get some thoughts, commentary, and suggestions on this? -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.
