Hi all,
Latest update.
With some help and phone calls from Bill the fault seems to have been
isolated. I have removed Q11 from inside the oven and it is cactus. Q9
is also very suspect so I'm going to replace that for good measure.
Q9 is a 2N1701 in a T08 package. Thanks to various people I should be
able to track one down. Q11 is marked as 1854-0003 and that's an HP
internal number and all I know. Might have to substitute that one.
After all this I have some quality photos and can knock up some good
descriptions of the repairs and the 106B internals if anyone is
interested. Any websites hanging around that want to take what I have?
Regards and thanks to all!

Jim, the 1854-0003 is a pretty common HP part in older eqpt. If you have
junked 5245L counter handy, it's full of them, especially in the decade
counter PCBs. If you don't have one handy, I have an assembly here with 8
of them on it. If you like, I can send it right away (if you're outside the
USA, you pay postage).

I went to a bookstore and asked the saleswoman, "Where's the
self-help section?" She said if she told me, it would defeat the
purpose.
