I didn't say there are any mistakes. The design is refined to the desired specifications of the author(s) and there is nothing wrong with it. It is entirely my problem that I want it to do somehow different, and there is no guarantee you'd like my mods. For example, I'd want it to have a much slower motion response, yet it takes quite long till it stabilises (if ever) and most people would not like it at all.

Hi everyone,
I noticed, that in the latest versions (ver. 2.0 and 3.0) of the scheme are added some components, missing in the initial versions:
Q8, R42, R43, R44, C25
What is the purpose of these elements - to maintain the threshold to be calm or...?
Since do not have the opportunity at the moment to experiment this circuit topology of this type of schemes but I am curious about this and I'd like to comment on it... What are your opinions?

hi
I build the pcb eduardo1979 put in page 17 (S.M.W.555.zip)
but when i turn S.M.W i have just noise in speaker and volumes not working
the amplitude is just working and when i turning it; the noise is going to down
i use BD140 in replace of bd135 (the back of BD140 is Side to 479U and Forward of it is side to 7809 regulator)
can anybody help me please...
