New 70MHz Amplifier

6/9/2010

I have been given a Kathrein amplifier that has just come out of commercial service on 71MHz. It is in a 19 inch rack mount panel, runs on 28V, contains a pair of isolators (with DLs) and is rated at 100W according to the panels. I haven't started to take it apart yet, but wonder if anyone has any info that can help me get started.

I have posted a few pics below if that helps....

Hi Steve.
I have been using one of these Big Kathrein Amps on 70MHz for several months.
I have details of the conversion for linear operation here.

If the page fails to load try again in 10 minutes. Atspace has been a bit slow recently.
