The new focus coil is installed the Philco- no more burning there, old flyback still in. But though screen of the horz. output tube is fed the right voltage of B+ once the tube *warms up* it plummets to like 70 volts from 260 even though cap plate lead is off. Grid input voltage is a little off specs at -55 (listed as -60). Another mystery.
