Symptoms: DNG RND CLC outputs a thin oscillator sound without the digital noise present. other outputs are fine.

It sounds to me as if there is an oscillator that drives the digital sound source and only the driver is functioning.

If I make this simple connection the unit sounds good when something is patched into the ext. Clk input AND can be tuned.

I spotted following chips:
cd40106b
cd4006
cd4070

Please let me know what the others 2 are and if these are correct.


Thank you.
