Predicta 17er still no negative bias on hot

while I still have not figured this out I have gone through the circuit board as best as I can. I have traced all grounds and appear to be good, all tube sockets meter good too..interestingly enough I have encountered yet another issue I am hoping someone can help me with...the width control seems to be getting very warm. 280v on wiper(vr tests fine) 27 to 50v at other end at hot. I guess without understanding how the basic hot circuit works I was just hoping after going through the board again I would find something obvious. I checked and rechecked my stake connections. Almost impossible to solder without sanding them down. I just don't understand how just moving the chassis a couple inches caused such a huge failure when it had such a nice picture for a few minutes. B+ seems to have jumped about 30v too. I have found another working 10L43 chassis that I am hoping will help me troubleshoot this with my limited knowledge of tv circuits. In the meantime any help would be appreciated.
