Nonsense Frank... I have built amplifiers at 40MHz with these MRF173s
with no problem.


Uh-huh. That's why you are unloading them at a fraction of the market
price, right?


That's like saying since a 2N3055 has an Ft=2.5MHz... that you couldn't
use for an audio amp... or they would blow up... LOL


Incredible..... how do you manage to stick your foot so deep into your
mouth? The 2N3055 is bipolar, has a relatively low input impedance,
and is -INTENDED- for frequencies from DC through audio and up. Not
only that, your implication is that the transition frequency (Ft) is
the intended operation frequency when in fact it is the point at which
the transistor exhibits unity gain, making it pracitically useless at
that frequency.

So where's that schematic, Brian?
