RCA console

oh the way I found the offending part was to feed each section of the maggie with pure 6v DC to the heaters. I used a big ole gel cell battery, started by feeding the entire sets filaments, bingo wave gone, this confirmed it was a filament AC source issue. Next I one by one reattached each filament group until I got to the deflection board where it returned. Sounds drastic but I was a real newb and was totally frustrated by it so was determined to try anything. I almost was going to build a DC power supple just for the filaments but that would be a real cop out. Anyway once I narrowed down to that one pcb I decided to solder on a ground buss using some solder wick. the orig ground was nothing more than a pressure contact of the pcb to the metal chassis thru a screw. I prob could have gotten it going by just tightening down the screw (and cleaning up the contract point) but figured the copper braid would be a bit more secure. I had a more recent "hula" on a RCA ctc 16, I think it was just a bad filter cap but dont remember for sure. It was one of those deals where the filter can tested ok and worked for several months then failed.
