Thanks to all.
It was Q2906, with about 50 ohms leakage. I happened to have an RCA
transistor #147665 that also crossed to an NTE159 that works great.
Funny, this is a lum buffer transistor,not a red driver, but why did I
get a bright red flash? not green or blue?
And what made you zero in on Q2906? Would not be my first choice.
;-)
BTW I will also change CR4118 as precaution before it leaves the shop.
