Triangle , the original settings from the factor is wrong - symmetry(Spike)
Solution:
use a scope and check your waveform and correct this by turning the trimmer TRI Symmetry
Thats not a Sine wave !- wrong settings from factory
Solution:
Purity - bends the TRI to a Sine wave - after this check the voltage to 10VPP (adjust the gain)
Filter Frequency, the Filter closed at 100hz instead of less 10hz
Solution:
Move 1 VCO to top in the VCF mixer and try to close the Filter, the signal must stop at 10-20hz Initial Frequency settings., not by 100hz or more, just turn the Trimmer as shown on bottom picture. (read the TTSH calibration guide too, to understand what you do)
