Hi
I have a copy of the original circuit diagram and was wondering if the latest kit from Hart Kits is different.
If so has anyone got a copy or link to the updated CD.
Regards
John

The transistors could be just about anything, not very critical.
If we talk european transistors
BC55x
BC54x
BD139/140 etc etc.
