u r corrcet. but 5w risistor and power mosfet mount up or down, so i create manual easy to mount mosfet and resistors.
this is a LAY file....
hi this is a LAY file..
hi this av400.zip LAY file one error
look this correct LAY file

An externally hosted image should be here but it was not working when we last tested it.

Have tried to project ??
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?
