[Amps] Dentron MLA2500

[Adrian Rees]

Hi all

Take a look at this PDF File from the late Kris Lund.

My MLA2500 has a crazy problem on 3.5MHz. I can tune it up with, say 10
watts. It'll have a input SWR of 1.5:1. Once tuned (into a dummy load) I
lift up the drive power, and the input SWR goes through the roof. Like 20+
:1.
The individual Band Capacitors are all OK.

On all other bands its fine.

So I am going down the route described in the article by Kris Lund.
