My manual lists the 4 finals as 2N6456's, not 6465's.
NTE crosses to NTE325, with the note that there are  "minor mechanical
    differences, but will fit most applications".
RCA crosses to SK9607.

The question is whether or not they will fit the heat sink.

NTE lists some ZN's, but no ZN6465. The 2N6465 is an audio power amp,
while the 2N6456 is a 50W RF power amp.

rfparts.com lists the 2N6456 at $29.95 each, so I'd look at the
others first. Let me know if you find a cheaper source.
