Hello all,

We either had two bad preamps to begin with, or they became casualties during transport to K4T, but regardless--the Icom preamps we took appear to have bad GAsFET devices in them.  

Can anybody tell me what is the device in each unit (AG-25 and AG-35)?  And are they something a skilled ham can reasonably replace?  

Specific suggestions for a parts source will be appreciated, too.
