Thank you, yes it is a 2N4091, my fingers are getting bad. I think I am
going to try a TIP122, I have plenty of TIP31C's, to much trouble and money
for a single 2N4091 when you take into consideration the age of the unit
and lamp voltage shows 6 volt.

I think it's a 2n4091, from the parts list and schematic. 2N4021 is a
PNP bipolar, 2N4091 is a N-Channel JFET.
2n4091 is available here:

I'd think a 2n4392 would work, Mouser has 'em, along with the TIP31B.
