[Antennaware] My Sad History from FL2100 (Eduardo Somoano)

[kg7hf at comcast.net]

Hola Eduardo,

My daughter and I have spoken to you many times in the past.   It seems maybe the valves have been damaged, I would have thought the two 47ohm in parallel would work as a replacement.  You might have better luck with asking this question to the amps group: amps at contesting.com
