I'm bored (DIY oscillator)

[saturated]

Btw sitting here doing some thinking

The circuit that worked utilized capacitors 100x smaller than what I tried 

And the resistors that I tried were orders of magnitude larger 

So going back to the original generic schematic that I could not get to work....it used the polarized capacitor symbol so hence I used electrolytic capacitors in my trial runs. 

Also referring back to the schematic for the tube generator and I presume MFD means microfarads but idk

You cannot view this attachment.

But it could be that there's no reason to compare the two (SS vs tube) because they are completely different animals

At any rate I may try using the smaller capacitors and resistors and see if it works

So the original generic configuration that was attempted I made a big reduction in values for resistors and capacitors

Increasing the power supply slowly I noticed there was something that rapidly appeared and disappeared as voltage continued to increase

So I went back to the narrow range where it would appear and carefully dialed it in and got this

What's wierd is if I decrease voltage the frequency decreases and if I increase voltage the frequency increases 

Because it was bugging me that amplitude was not responding to voltage level 


Before I shut it down I decided to write down some voltages

The first set is taken when there was the visible waveform or apparition or more likely abberation 

Then below that is when the voltage was increased to cause the abomination  to collapse and become a straight line

Hmm looking at this I don't think the base is supposed to be more positive than the collector but I'm not sure

Maybe I need to increase the Q1 base resistor
