Tektronix 2235, A/N-USM 488 Horizontal Alternate Intensify Error

Any quick check for A intensify always running to end of A trace regardless of B setting?
Start of intensify is correct and moves with delay time and B trace is correctly displayed.

Found Q643 (Tek 1510190-00) with OC emitter junction and temporarily replaced with a 2N5961 until Tek replacement arrives.
"A" intensified now works correctly.
