AMPVHF - Tech Special 2m and 6m Solid State Amps

I have 3 solid state amps that need repair.
I'm interested in repairing myself if you're willing to talk me through the process.
OR
Willing to sell as-is. Make offers and specify if they include shipping or not.
-
1. RF Power Labs 400 watt 6m amp. Was working fine, now no amplification. Don't know of anything done to damage it.
I hear relay click but no increase in power output.
-
2. TE Systems 1452G 350 watt 2 meter amplifier. This was briefly (a couple of seconds) transmitted with NO antenna connected. It since draws current and heats up if connected to DC power source.
-
3. RF Concepts 2-417 45in 170out 2 meter amplifier.
Power LED turns on but otherwise there is no indication it's actually turned on. No relay click or anything. Just the same as if it's off. Power out is the same whether amp is on or off so thinking it's lacking something in the power on side of the circuit? Preamp seems to work and makes the relay click etc.
