http://www.youtube.com/watch?v=Ihg3M61uV6o&feature=youtu.beI have completed the assembly of the 9720 VCO. I have begun the testing scenarios from the assembly manual. I am on page 18 at #4 of the testing portion. It says "Each should be a low pitch and of equal amplitude".
Osc A and Osc B have somewhat similar amplitude, but the pitches are not at all within each other's range. Furthermore, the voltmeter does not match the suggested ranges.
I have checked IC4, Q2, and Q3 as well as IC5, Q8, and Q9. All of the connections look solid and placement appears to be correct.
Also, when connected to the MIDI to CV converter with a midi controller, the VCO does not track as expected.
To be honest, I am fairly new to all of this, so I just wanted to touch base and see if there is something wrong, or if this is normal.
Thanks!
