Cook Book - few more lines

as always - Cook Book supplemented with few more lines ;

they are :


"- My mistake was that I wrote ZY10 zenners in Shunty (D1 to D5, D1ato D5a)
; all you need is ZF , which are just generic 400mW ones ; now corrected in parts table .

- In case that you are fluffy with setting absolute offset (DC voltage between plus and minus
outputs of Pumpkin ) , you'll have replicated DC on both INPUTS of Pumpkin ........ exactly
divided by ratio of feedback net .
That will result in screechy noise during volume pot turning .....
cure is simple - Papa-like ....... just include 2u2 good cap on each input leg (both + and -)
between pot and inputs ; that will block DC to reach pot .
Hehe - that cure is certainly less evil than using any kind of Servo"


regarding these caps - Holger (HB) already sez long time ago that he even will not try his :Pumpkin: without input caps ......... :D

as usuall , Cook Book can be found HERE
