Hello, What are some examples of oscillators which don't require transistors or vacuum tubes? So far I found relay oscillators and the Pearson-Anson oscillator. Does the Pearson-Anson oscillator require a high-voltage neon lamp, or would it work on LEDs as well? https://en.wikipedia.org/wiki/Pearson%E2%80%93Anson_effect Relay oscillators look neat too but I don't imagine they would la...

I see lots of tube amps with the tubes mounted such that they point down. This means all the heat rises up into the chassis. This seems counter-intuitive to me. All those components baking all the time. Is it just for convenience? Eric

I was thinking of making a DC (slow) x100 'scope probe by adding a series 100 meg ohm resistor. Any thing I should look out for? George H.

Is this possible? I have a customer, a glass artist, who uses several very nice but old glass grinding machines. There are only 4 speeds on these machines and he would really like more speeds. He has a newer machine with a VFD on it and asked me how he could get the same thing on his old machines. I told him he really needs to change motors to 3 phase. But he is loathe to do that. I can see w...

Is it reasonable/possible to build an 8 amp 20 V transformerless power supply from a 120Vac line. I calculate about 180uf plus or minus depending on other components. Maybe 9- 20uf caps in parallel? I'd like to build it into a leaf blower. All plastic, absolutely no metal exposed. I think I've answered my question, I have 12, X rated caps in my junk box, but they are only...
