(Moderator's note: This thread was started by moving posts #1 through #13 from the following thread: https://forum.allaboutcircuits.com/threads/12-mhz-oscillator-with-a-voltage-range-120v.148686/)
Everyday I am producing 40-100 MHz generators with falling characteristic slope (=current source=serial resonance) of ca 2000-5000V at 100W...200W...1000W. Their Vcc is between 24 and 30 V DC.
If Your demands stay ever near, You may ask me about circuitry and grand stoppers. But if Your interests are hard output slope (=voltage source=parallel resonance) then I cannot help very much as only to refer to ANY small spiral-like incandescent lamp circuitry. Find one dead, go to the place where EPA inspectors dont see You, and extract the transistors. Every contain the 400V (CE) or 600V (BC) pair, most often it stays CD13003 (TO-220) or 3DD4202BD (TO-92). Both has F(T)=4 MHz.
From higher power devices still at about 5 USD pricing stays 600V 15A and declared 40 MHz however capable for near 100 MHz the ixfh42n60p3 and slightly less powerful but twice faster apt6038bll for about 10 USD.
