[VHFcontesting] Lunar PAG 432 Preamp device

[Rogers, Ron]

Dex,
I looked through my library of files on preamps, etc. tonight researching my old Lunar stuff.
 
I ran across some old PAE and PAF preamp sheets, but not the PAG.  However, I did find a Lunar price sheet from May of 1980 with some info you might find interesting.
 
The PAG 432 preamp was listed at $125 Amateur Net in 1980. 
 
What I also found on the sheet were the normal replacement parts and pieces. Listed with the bipolars, J-FETs, and dual gate MOSFETs, there were 2 UHF GaAs FETs listed to chose from. 
 
The MGF1400, and the D432 Dexcel device. 
 
So, my guess is that these were the devices used in the PAG-144, 220, and 432 line of preamps. 
 
If you like, I can make a PDF of this sheet and e-mail it to you..........or bring to the conference this weekend.

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 :)
