Hello, I just got finished putting the CP5176 kit together. When I tried the set up it failed to change the output upon adjusting P6. Input voltages are +/- 15.6V as expected and -5.45 V is measured at TP7. Upon further investigation, the DC voltages check out fine at the test points of A to G. However, I am measuring about 40 mV DC on L1. The output AC voltages from TP3 are much higher than expected with a 100 mV signal at 1KHz.
Outputs are as follows:
Ratio 2, 2.8 V
Ratio 4, 5.7 V
Ratio 8, 9.8 V
Ratio 12, 11. 4V
Ratio 20, 12.78 V
Slam, 12.8 V
No AC voltage can be registered for any ratio on TP4 or pin 1 of JMP1.
Looking for some advice where to look next.
