I completed the amp board and adjustments with approx 30 watts at 14 mhz. When I added in the filter board and tested it, it appeared to work too... relays clicking, etc. All of a sudden, no power output from the amp.... a "small jump" in the watt meter (less than a watt) and nothing. I can hear the PTT relay kicking in. There are no apparent fried/burned parts.
  Amy suggestions on how to trouble-shoot?
