This circuit is from a 1966 publication. The frequency depends on the capacitors and on R1 which can have values between 47k and 2.2 M typically. The supply voltage can be between 200 and 300 V.
Other operational amplifiers in the series, such as the MC34072, MC34074, MC35071, MC35072,...
This circuit is from an old RCA MOSFET manual from the 70s. The circuit can be implemented with...
