Excellent !
Than you can do some experiments:
- test how much it takes from the power on moment to got final stabilised
oscillation ( amplitude and frequency )
- test what's happened if you switch on and off a maximum accepted load
- test what's happening with your frequency and amplitude if you blow hot
air on your oscillator.

best regards, Vasile
