VCO Sub osc pulse width?

VCO Sub osc pulse width?

2009-06-24 by Jon

Hi,

Mine is just a short spike. Giving a very thin sound.
Should it be like that?

The 220pF between leg 1 and 5 sets the width?

Cheers,
//Jon

The capacitors were 330pF on the original version, and are 1n5 on the later
version, and yes it is a narrow spike. These days I don't rout the signal to
the panel myself. Have a look at the second panel layout on my page.

I'm sorry I wasn't clear - I meant the Sub Oscillator circuit on the VCO (CGS48).

Thanks!
