Thanks again for the help people.

I think I'll take on board both your comments and start off with a 500R resistor.  That'll give me base current around 7-8mA which should be ample.  Besides, it just so happens I've got a whole load of 500R resistors lying around!!

Are you sure 500R is an unusual value, a value of 510R is more standard.

I knew that!!  :smiley-red:

Slight shlip of the mind!  Yes of course you're right I did mean 510R, my brain hasn't woken up in a while  XD
