Oscillator Circuit
#1

Hi All;
I am building an Oscillator Circuit based on my Philco 34 Radio, I am using as a model the Philco 39, since it is essencially the same circuit, except that the 34 is a four Band and the 39 is a two band Radio.. The Philco 39 is simplier to follow..
What I am asking is -- I want to using my scope find out what frequency the oscillator is oscillating at, So I figured that If I connect a Capacitor to the plate, I can measure the frequency from the Cap..
What size of CAP should I use ??
The tube is a 1C6 Pentagrid converter, I am only going to hook up the oscillator part of the circuit, and not the RF, that would only be hooked up thru a resistor to -3 as per schematic..

THANK YOU Marty
