In your circuit there is nothing to limit high frequency components of your
audio input from modulating the screen of the power oscillator. You a...

Yes, it is an AM modulated radio transmitter, you just have to hope that the "antenna" is ineffective, and no radio hams with pitchforks live nearby. ...

I test it with a frequency counter.It easily detected the signal several meters away.The frequency is about 8.5MHz. But my scanner cannot pick up the ...

The 6V6 looks like a really weak tube. The 807 is better, but still a lot weaker than color TV horizontal output tubes. The horizontal output tubes ha...

If I use 6V6 or 807,Should I change the anything on the schematic?

PL504 is weaker, maybe you could get the Russinan 6P45S tube?

I cannot find 6P45S either.But I can find GU-50.Will this work?Or I need a different schematic if I use GU-50?
