I assume you are referring to T2302, there are no 28xx parts on the PA deck. I
suspect what you are seeing is one of the lead wires from T2302, which is part

The gain control circuit in the Drake may not have enough range to reduce the
output enough. You are quite right, in that you DO NOT want to overdrive the
amplifier. There are various ways to reduce the output of the transmitter, and
some amplifiers have internal options for high/low drive level.
All of the radios and amps that I have seen use a negative ALC control voltage.
I suppose some newer solid-state gear could be different, but I don't know.
Perhaps someone can enlighten me. Where the amplifier has a level adjustment
control, compatibility issues should be minimal.

As I recall, the gain pot on the V1 predriver was problematical; Drake service
notes basically said to leave it alone unless you absolutely have to adjust it.
Other than that, I'm just making a wild guess that the V2 board may bhave been
a cost saving redesign. Someone else may have more info.

Yes, that fuse is your first thing to check. Even a nanosecond short on the 12v
rail will instantly take out that fuse. They can also fail from years of
stress, or there could be oxidation on the fuse holder. It's not quite as hard
to change as that, but it does require some dexterity. I usually p

Lincoln,
Chris,
I can check Monday for you, I work in the Telex service center. Very slim
chance, anything related to end of service products is usually disposed of
forthwith these days, but we might get lucky. At any rate, it's probably not

You can keep the mic gain down and reference a PEP reading wattmeter. This
