Two little Predicta questions

[leadlike]

My Predicta Princess has the same issues-correcting a horiz. lin. issue on one part of the screen just causes another one somewhere else. This is the only set I have with the adjustment just being a magnet, so maybe that's the best it can do.

I'm still too much of a weakling to get that spring back on, I lengthened mine with a bit of wire, but now the spring is too slack to really do its job.
