But does it have a max temp cutout?

No, but thermal and excessive SWR protection are slated for future
versions.

Good, I am happy to hear that, even the most simple thing you can buy here has
these thermal fuses, all AC/DC adapters, any coffee machine, heater, almost
anything.

I dunno any of your design parameters, but say if your heat sink is 1.5 degrees
Celsius per Watt, your transistors .5, and you run 80 W dissipation,
the junction temp would be 160 above environment.
If somebody has it in a car with sun on the roof, chances are you cook the
'pils'.
Even a 60 cent one time thermal fuse... so much nicer to replace then
2 transistors.
So I am looking forward to seeing such a feature.

SWR is of course good to have too, my old antenna did behave bad in storms,
the new one is OK, but I still have an audible alarm and red LED on the SWR
meter :-).
Automatic would be better.

I hear what you're saying... but my future design will only include
thermal protection that will restore operation, once the excessive heat
event has passed.

So what you are saying is consumer beware considering your amp taking a
**** because of excessive heat? Why not build your amp so the blind dont
waste their bux? Or is it cough a money making scheme you are up to?

Thanks for your input...

Jim does have a point Brian. Remember, we're dealing with CB'ers here.
