On second thought, I am pretty sure it would damage the pot. At 150 ohms, it would draw around 200 mA and there would be more than 1 watt across it.

Hi maybe i missed something, but a regular push pull, using 2n2222a and it s conterpart 2n2907a can give good results at 1Mhz, as long you keep input resistor around 220 ohm or below if possible. In order to do so, you have to use 2 schotky diodes insteed, which greatly speeds up response time, installed between bases and collectors ( blocking sides toward + nodes, of course) such as MBR150. It drives fets satisfactory. Rise and fall time are about 25ns each (to 90%). Try this out ?Exidor said:I wanted to avoid inductors. I need a two phase square wave at 816.5 KHz. There would be high voltage around so I wanted to go with transistors instead of IC's. The output signals drive a transistor amplifier, which would feed the primary of a Tesla coil. I could use a CD4046 and an inverter, but the chips might get burnt out.
