Thanks for the info. I have a friend here who has one about a year old and
was wondering about that. 73

The newer ones have a whole different suppressor scheme than the older ones.
if this is an older amp you can update it with the new parasitic board
designed for the newer 811H amps. If this is a newer amp and already has the
updated suppressor board then there may be a different issue. The older
811H amps I don't think were neutralized. The newer 811H amps are
neutralized.

On the 3830 contest reflector someone posted a comment that "The AL-811H has
a know problem of the parasitic chokes burning up on 10 meters." Is that a
true fact on those amps? 73
