* RECALIBRATE THE OSCILLATORS AFTER DOING ANY OF THE ABOVE MODIFICATIONS

*********A**********
1. Check Mains voltage setting.
2. Plug in Card A only. /!\
3. PSU Switch on. Adjust VR2 for +12 volts. // voltmetre
4. PSU Adjust VR1 for -9 volts. // voltmetre
5. Plug in Cards B and C.
6. PSU Recheck +12V and -9V. // voltmetre
7. REVERB Adjust VR3 so that mixing occurs above 2 on the Reverb Mix knob.
8. REVERB Check the voltage control of reverb mix.
9. O/P Adjust VR4 and VR5 for zero residual signals. // osc signal in 1 et 2 / volumes à 0 // pas de son OK
10. O/P Check the tracking of Level knobs 4-5-6.

*********B**********
11. ENV Set Trapezoid speed to 65Hz with VR12 // env 0 0 0 0 0 0 trapez out dans in 1 65Hz // voltmeter freq hz ou soft
12. ENV Set VR13 clockwise. // osc dans env in, volume env 0
13. ENV Adjust VR7 for minimum residual signal. // pas de son OK
14. ENV Adjust VR13 until signal just reappears, then back off to zero. // pas de son OK
15. ENV Check that maximum On time is at least 4 seconds.
16. ENV Check that maximum Decay time is at least 15 seconds. // ON R148
17. ENV Check that recycling occurs with Off set at 5.
18. ENV Check that recycling does NOT occur with Off set abaove 7. // OFF R143
19. ENV Check that Trigger functions and does not jam.
20. FILT With filter in oscillation and Frequency control on 5, set VR6 for 261Hz.
21. FILT Check that Response control gives filtering below 5 and oscillation above.
22. FILT Check the shape of the oscillating Sine wave.
23. RM Adjust VR10 for fundamental rejection on A residual signal. osc 1 dans A in // pas de son OK
24. RM Adjust VR9 for 1st harmonic rejection on A residual signal.
25. RM Adjust VR11 for fundamental rejection on B residual signal. osc 2 dans B in // pas de son OK
26. RM Adjust VR8 for 1st harmonic rejection on B residual signal.
27. RM Check for frequency doubling when both inputs are the same.
