After over 25 years of use with no sequencer my Lunar PAG 432 preamp
died. I'm fairly sure a DC input spike killed it even though I have the
standard diode and capacitor spike circuit across the input. I had just
moved the 12 volt input to a difference power source which also supplies
power to a pair of old Dow Key relays.
So I am in need of the original device number used in this preamp. I
could not find the documentation that came with the preamp and A Google
search didn't find the info.
I have a quanity of old but never used Dexcel FETs designated as D432.
I seem to recall building a 2 meter preamp using this device in a
circuit designed for a MGF1202 and it worked well. I believe it got
sidetracked to a repeater project years ago. Anyone know the specs on
this device? I'm tempted to try one in the PAG432. The numbers match :)
