?Hi Chuck,

Good point. So far it's stable. I aligned it as best I am able for now, and it's working in all modes with reasonable accuracy. If it becomes intermittent, looks like it is still possible to obtain these FETs, though it will probably cost.

Just a repair note:

I have seen a lot of TO92 packaged transistors where
one or more lead has become intermittent. I believe
this is caused by fiddle fingered folks that just have
to push the transistor around to match their ideal of
position, or to read the number.

It always seems to happen when the transistor is mounted
with the leads in a tripod position with the base lead
bent forwards, or backwards.

Touch, or otherwise move the transistor, and it quits...
touch it again, and it works.
