I do see one problem with this basic mod that is easy to correct. The center tap on the input transformer has been isolated from DC and RF ground. That's not right. It should only be isolated from DC ground and returned to RF ground trough an appropriate RF bypass cap. Add at least one .01 uf ceramic cap between the two points cut with the Dremel. Keep the wires on the cap short to reduce inductance.
