Working on an old SB610 scope. Have replaced all components .. resistors, caps. Diodes are FB. Transformer voltages are also FB & what they should be. Checked all tubes & CRT & they are also good. But the trace line on the CRT jumps around - up & down.  Suggestions please where to look next. Thanks 73s Carl, k4zrd
