SOLVED Caesar is ill

Have a nice day, everyone!
Please help if you can - the Caesar chorus part is not working.
Try to ignore the voltage and op amp names in schematic - it just fits.:)
I hope it will be easier than 23 wounds.

3207 voltages
1) 0.00 8) 3.95
2) 4.20 7) 3.95
3) 1.06 6) 4.17
4) 8.06 5) 8.64

All LEDs (and 3mm) work as they should, 5mm are temporarily not soldered. The flashing frequency is successfully adjusted by pots.

UPD: the blend pot works like a reverse volume - at the max the sound disappears, at low values - quite loudly.

Thanks you all for helping.
Thanks to your support and participation, I did not give up and continued troubleshooting.
I rarely make mistakes, so I could not think that the problem is so obvious. Trim did work, but did not biasing. I rechecked the nearest things.
It turned out that if you solder the cathode to the minus, and the anode to the plus, and not vice versa, then adjusting the trim is much easier. 47mf, C102.
Everything works, still more lucky than Julius.)

My mnemonic is Anode is like A - like Andro

Men are + and women are -

+ is good and - is bad

The + lead of an LED is longer, like a penis.

and I NEVER wire anything incorrectly...
