Hi All;
I GOT it to OSCILLATE.. And I can vary its frequency..
The Extra Cap accross the coil, for some reason was preventing it from Oscillating..
I went back to my origional Philco 39 circuit.. And when taking out that Cap which was a trimmer, I had planned to try some fixed caps, it started to oscillate..
I don't understand "why" all I know is this proves the basic circuit works..
Now to modify it to work like the Philco 34.. A slight modification.. One side of the coil and the Cap are reversed in the circuit..
THANK YOU Marty
