[TenTec] 560 Problem

[Stuart Rohre]

Well pretty clearly, this amplifier stage has been blown.   I think the RF
amp is really in the IF, but look either ahead of the mixer or right behind
it.  You should be able to ID the oscillator for the mixer and its
connection to the mixer.  Then, this amplifier is either connected ahead of
the mixer to the antenna, or right after the mixer toward the first IF.
