Sorry I'm not sure how I made my mistake Les.

I looked at the Datasheet for the BC008 transistor that Bill suggested and it was a PNP. I didn't think that I could swap a PNP for an NPN. When I said "called for" I was only talking about the three transistors that Bill said I should check.

Over the years I have heard techs use the term "called for" as in "the schematic calls for a 100R resistor" or some such.
