T%his is in reference to the pass transistor in the M-II PA power control 
circuit, (sometimes identified a Q 215)..  In the mobile units this transistor 
is the TO-220 type. In the continuous duty station transmitters it is a TO-3 
type. My questions are if you put a mobile transmitter board in the station 
heat sink assemble will the TO-220 transistor be ok with continuous duty 
operation?? Also,is the power control circuit the same in the mobile and 
station transmitters, so that you could remove the TO 220 and wire in a TO 3.  
Thanks. Sid.
