From the post

Hmmm this looks familiar to another layout I've done recently ...

Note that at least one of the transistors is going to be very difficult to obtain now, and/or will be expensive. The pinouts shown in this layout are based on using more modern transistors as replacements such as the 2N3904 or 2N5088. Check the pinouts for the transistors you decide to use before soldering.

[Note: Layout updated 20th June 2014]
