Jose,
The fact that Yaesu output drops to 20 w seems to be an important symptom.
There are two things that cause Yaesu output to drop:
A) VSWR too high at output of Yaesu -- check input vswr of amp. (something at
the amp input may be bad)
B) ALC circuit in amp is giving too much feedback to the Yaesu (maybe it's
broken) -- disconnect the ALC and operate the rig with manual control of Yaesu
output.
