From the project

Initial Analogue LFO - Mult/Mix - NAND/AND/NOT - FlipFlop - 555LFO

Analogue LFO - minor adjustments - new jacks (PJ321 -> pj324) - remove Sine Adj

555 Based LFO - minor adjustments - new jacks (PJ321 -> pj324) - remove XXX

Bottom - 3 mult output with phase reversal - uses mixer output as input if not applied to mult input

bias current compensation (eg. 10k to GND)

2 - Sine pot should have 2k series resistor

3 - C303 could be 100nF and 1uF addon with a switch for high low
