On an other note, instead of the trusty 2N5109 a BFQ19, a modern rf
transistor, can be used.
It gives slightly better IMD figures in this circuit, especial at lower

The only BFQ19s that I was able to source were SMT. Did you get them in another package? 

Did you need to use a heatsink with this transistor?
