In answer to Bill's question: C=113,B=114,E=102
Usually transistors will have between their bases and emitters a
voltage difference of 0.7 (if silicon) or 0.2 (for geranimum). Unless
the transistor is biased off (passing no current). Where is that
color killer trimpot set? Looks like, depending on the setting, the
base voltage could be anywhere between 0 and 300V. Adjust the
trimpot so the base voltage is what the Sam's diagram says, and
then check to see if the other voltages around the transistor
are close to what Sam's says they should be.
