A while back someone had this problem & was never solved.
Also had one at the shop years ago but never followed up
on it.
Although its the upright chassis this refers to they are near
identical electricly. From TP-11 training manual
1) lead dress of the wiring between the 22-5001 caps.
2) getting into IF module via the 24V B+. moving the B+
wire to a different point cures it.
3) I also personally think the replacement triplers may be
the cause or other lead dress issues. It would be nice to
see a true virgin set to see the dress of the HV, yoke, CRT
and convergance as the factory made it.
