Hi Bruce, The old Acrian FM-150 would fit that outline & description... now if you can just find the right time closet. :-) 73 & Good evening, Marv WC6W -- Bruce Brackin wrote: The original finals are 0.5" stud mount (10-32 stud) and given amp specs, it sounds like a 28v NPN rated at about 5w in and up to ~ 100w out cw/fsk or 150w PEP rating at 50 MHz or about 12db gain figure for each. Open to suggestions and TNX in advance - Bruce, N5SIX _______________________________________________ ________________________________________________________________________ Try Juno Platinum for Free!
