Kevin, maybe you could contact Ed Jackson, WB2OIF...he worked for Gil Boelke for several years
and may know the answer to this one...

Subject: Re: [Repeater-Builder] GLB Part


Hi all, I am looking for a transistor that's in a GLB Preselector-
Preamp.  This is for the two (2) meter band.  Here's the information 
(best that I can see)   M (batwing) u 901  Thanks in advance
    

That would be a MRF901.  RF Parts used to carry them.

Here is a bit more information after googling around:
<http://www.simrex.com/site/products/preselector/preselector_diagram.pdf>

<http://www.aria-glb.com/products/reset_frames.htm?/products/preselector.htm>
(ignore the extra '1' in the "CENTER" column)

These two are right:
<http://www.aria-glb.com/pdf/Preselector.pdf >
<http://www.simrex.com/site/products/preselector/Preselector.pdf>

Remember, the GaAs FET option was only available on models over 200 MHz.
I'm sure the part is a Motorola MRF901, but I'll look some more to be absolutely certain.
Unfortunately, not much information accompanied a new Preselector/Preamp, and I can't even find what did come with the several I purchased over the years.
