I've several of their 15-1109 preamps with blown mosfets. The only replacement ones I have are not capable of standing the source voltage (12vdc+) for very long. Can anyone suggest which mosfet (surface mount or conventional) I should use?
While I realize this amp's noise figure could be better, the one I'm using allows HD reception from 100 miles out using an old Channelmaster parabolic UHF antenna at 60 ft being fed by about 90 ft of RG-6. I'm located some 60 miles south of Buffalo, NY and about 100 miles from Rochester. The fine educational station (WPSU) at State College, PA also rolls in nicely
Tnx, Sid
