The supply voltage is too high (13V). The BOSS brick does not seem to be a regulated supply. The voltages on the ICs do appear to be correct (at 1/2 of the supply).
The SW2 is wired incorrectly. You are only connecting Lug 2 to Lug1 which is used to provide a fixed voltage for the “Kill” function. Move the red wire to the lug next to the two green wires. The switch should connect the LFO and you should get a varying voltage at the anode of the NSL-32.
The pictures helped.
