The replacement shown has the focus built in.
It is not a direct replacement at all but could be moused.
The OEM ? in the set uses the divider resistor, the plastic part
with the other big red wire etc.
If you go further with it get the ##'s off the tripler. If a ZENITH
OEM you should find part number 212-141-## on it.
Also be sure that big resistor isnt burned. Bad triplers sometimes
burned it.
