How could I not!

Living remotely in the jungle makes getting parts difficult so I have a lot of time to test and read schematics, but experience is invaluable and being able to bounce possibilities while I wait for parts from the USA that come with visitors.  Luckily the small electronics shop got some 733’s in, 6 months ago they only had the NPN’s.
