Yes, no improvement. There's only about 50mV ripple on B- but it does find its way into the cathodes of both horizontal and vertical multivibrators. Then it gets amplified along with the sawtooth. I tried tacking in a couple 22uF caps on B-, but it made no difference.

The only thing I haven't tried at this point is adding more filtering to B+. Since it's not used in the deflection circuits I figured why bother, but I'll give it a try.
