As shown, the sawtooth generator is made up by the 555 monostable timing circuit and feedback bootstrap circuit. The IC2 (LM741) operational amplifier is used as feedback bootstrap circuit. The 6 foot's output voltage would supply the sawtooth voltage's charging current for C1 through R1. The current size depends on the voltage regulator tube DW's clamp size and the resistance value of R1, which would change the sawtooth's cycle time and oscillation amplitude.
