Nope...it was really a plain simple NPN bipolar transistor
Actually...to be honest..it was a CA3046 which is a chip with 5 NPN
transistors on board....i was amazed it worked at all....but it did :-)

I made a little ascii drawing (hope you can read it...I'm a terrible ascii
artist) in a mail to Roy

Greetingzetcetera, Thom
