I am helping a friend build Francis Decks PIC programmer.  The only source
for the LM10 opamp is Farnell (in Britian) and the prrice is over £8
excluding vat. Can anyone supply a transistor circuit for this purpose (5V
>from pic when on giving 14V programming circuit and 0V when off).  The
emitter follower circuit can't be used due to the effect giving only approx
5v out so a dual transistor circuit must be used.  Does anyone know a
circuit that would work?

Thanks
