Gonna try to make an oscillator based on this

You cannot view this attachment.

I have no idea what values of resistors or capacitors to use

Nor do I even know what where the output is

I presume B+ is gonna be DC piped in to two places

Anyhow I looked in my box of junk and pulled out two ancient transistors hoping they were NPN and they are

Should be cool 😎

Did it work?

I just assembled this rats nest

Not knowing where to put the scope probe I attached it to the positive leg of C1

And it looks like the sum of all those randomly selected components has resulted in a malfunctioning diode

That being said hey I'm glad I got something

Maybe that "waveform" can tell me something  xP

So the only cheating I did was glancing at the tube oscillator schematic  xP

I noticed they were using much smaller capacitors

So I changed out the two 100 uf for 22 uf and played musical resistors for a while really no change but a cleaner rectified waveform  xP

I have decent Vbe on each transistor 0.7 and 0.65

Also voltage across the resistors going to ground  xP

So idk should be educational  :tu:
