[Amps] TE SYSTEMS 1412G

[ian swain]

Hi guys

I have a TE SYSTEMS 1412G that has a problem where with the amp in circuit
and turned off  ie by passed there is a high SWR and almost  no power
out the other side.

When the amp is turned on in operate mode it works fine low RF input
good swr
and high RF output.

I opened it up is find what looks like a sealed relay thinking bad or dirty
relay contacts.

Has anyone had this issue ? I have looked on the web for TE SYSTEMS
with no luck.   As I need a manual as well and circuit diagram.

Any advice is welcome.
