Hello.
I'm also building av800. After many many mistakes and errors i managed to get it through pre-flight test somehow.
But Q5 (IRF610) seems to be heating quite hot. around 60+ celsius.

I haven't yet tested the amp with o/p devices in fear of blowing them.
What is the maximum input voltage and should i use some sort of load in pre-flight test?
 
The amp in the picture (post 66) gives a little concern.

Looks like IRFPs are being used. Should there not be local decoupling caps?
From experience layout is important for verticals and not having local decoupling could be asking for oscillation issues? There doesn't appear to be any gate zobels either or are they soldered directly to the MOSFET pins underneath?
