Woke up early this morning so was able to swap out the BS170s before work. The hardest part was figuring out where they were :)
Well, also desoldering. The wick works good in general, but isn't good at clearing holes. But I managed to use the soldapullt on the other side of the board from the iron and it worked a treat. Would have been good to have a third hand or a helper, but made it work.
On the plus side, I have output! And gain! But not as much gain as I should have.
With a 13.8V power supply and 9v p-p from the signal generator, I was getting about 4.6W out (15.2 vrms). I am unclear on if that is too much power input. There are discussions on the forums about input impedance not being 50 ohms, so I'm not sure if that is 200 mW (at 50 ohms) or 25mV (400 ohms). Should try to get a proper power input measurement...
But based on things in the forums, I increased the power, and was able to get 10W at 17v. Can experiment more with the input power. But, regardless, I fixed it! :)
