That second character 'L' might well stand for 'line' which is the
conventioal name for the hoprizontal deflection system over here. We talk
abvout the 'line output trnasistor' where you'd say 'HOT'.

Were the transistors in the vertical stages called 'TF00x'? 'F' being
'frame' or 'field' depending on how old you are.
