Vert hold/control ?

[Electronic M]

Remember Sam's is usually only a snapshot of one random production run. Sets often had significant changes between and sometimes during production runs. Parts added, parts removed, values and or wiring changes, etc...Always evaluate what is there in the set for originality. If what is there is a factory part/connection then you can assume that is how it is supposed to be, but if the part is the work of an old tv repair by an unknown tech be prepared to doubt it (do note what the change was in case it is needed).
