Another problem - hopefully the last.....

So I was just putting the finishing touches to my 70cm DATV set up which included fitting a rather nice 70cm DCi bandpass filter on the output of the Dolphin TTRX power amp.
I had read that these amps don't like driving 'hi Q' filters as they can go unstable - well surprise surprise it went unstable, luckily no damage done.
Time for an isolator / circulator between amp and filter - fingers crossed that should fix it.
Any idea where to get one ?
