Hello all... does anyone have any experience of opening & repairing a 4027-1 oscillator? The pulse wave on VCO1 in my 2600 disappeared and upon testing I found that the sawtooth output from the 4027-1 core was fluctuating around 1.5 to 2v instead of the expected 10v... any advice or suggestions on opening & trouble-shooting the submodule would be appreciated. Cheers, J.
