VCO now at 4.55 KHz working in RW with bulbs

Good instability throughout the sweep with stable sweetspots, wide Voltage range but still low bandwith, which was not intended. Be free to pimp my circuit.
new log: now working with 2 12V bulbs in series at 9V 1.5-18V before a 220 Ohms res. BTs are 2x BC338, had them around, though with their 25V rating is a bit too small for experiments with oscillations. Lamps glow slightly.. while the filaments are heating up you here a rapid sweep until it tunes itself to a stabile frequency, steady glow and resistance. Cleaner that i had expected. Rapid attack.

Powdered and backhanded.
