I don't know what you mean by helper magnets. They are the static convergence magnets....You know how on the newer yokes how there is a knob on each petal of the convergence clover (yoke) to adjust the static convergence?....Well mine has those dumb white plastic sticks with magnets on the ends instead of knobs....They are less smooth to adjust than knobs too, and I can see why once the new kind was created they fell out of use FAST.
Zeno: I never knew Sylvanias had 20' cords. I can see that being useful for lugables and movable cart/stand dwellers, but it was probably terribly awkward on consoles.
I hate when wires are too short on table sets to use the set as it's own test jig!
I still have not found the damn magnet!
But if I do I'm gluing it into the plastic like I'm in the process of doing on the remaining two.
