Lose those awful sun glasses. Maybe you just can't see how to search for one of the 23,500 results.

Did you search for the answer, as I suggested?

Search for "Bubba Oscillator".

Hi Frank,

The problem is that you are missing the phase shift resistor that should be inserted between R1 and C1. Also usually the Phase shift should be set for 45 degrees for each stage so each of the phase shift resistors and each of the phase shift capacitors should have the same value. Also the gain should be = to -4 in the first stage, which I think you got right. (It is hard to read the schematic.)

Hope this helps,

Dan A
