Also, can you confirm that R27 is 4K7 not 47K, and R29 is 100R not 100K?


Hi Rick
Trying to read as much as I can on my issue.
So what should that resistor be 47K or 4.7K?
Your diagram states 47K for the VibraCaster should it be 4.7K ?
On this diagram it looks like it was originally 4.7k but the "." is blocked in the diagram.

I'm using a 47K on my board.

Yeah that resistor in the Vibracaster is 47K, I had to 'evolve' it from the LFO R.G. suggested to suit my transistors and the circuit I was using it with. A 4K7 in that position in the Vibracaster will make it tick like a Swiss clock at midnight!

OK no problem.
Darned I was hoping I was on to something LOL
Don't worry I'll figure out what I did to mess it up and it will probably be something simple and silly :icon_lol:
I think I know why the breadboard experiment didn't work last night. I thought the plus and minus rails on the sides of the breadboard were continues along its length. But they are not they are separate blocks one after the other :icon_evil:
I need to use jumpers. I tore it apart, will rebuild it again tonight.
