Hi Randy.

       Where is this capacitor and what value does it have? The PSN circuit 
on John Lahr's website has ieither a 1 or a 2 mu F POLYESTER coupling capacitor 
into 10 Meg Ohms, giving RC of either 10 or 20 sec, coupling to 60 or 120 sec 
periods?? 

       Regards,

       Chris Chapman

Hi Randy.

       Where is this capacitor and what value=20= does it have? The PSN circuit on John Lahr's website has ieither a 1 or a 2=20= mu F POLYESTER coupling capacitor into 10 Meg Ohms, giving RC of either 10 o= r 20 sec, coupling to 60 or 120 sec periods??
