Insane construction if it is really using a 1k/1k bias divider instead of using the second half of the op-amp as a buffer with a 100k/100k bias-divider for less overall current consumption (4mA only through the bias divider itself).Gila_Crisis wrote:this is another schem of the boost section, it comes from an italian forum.
the guy who traced it, reverse-engineered it from the MC401 Boost-Linedriver and it's verified!
oh well forget the flip-flop bypass section an build it with a normal true-bypass
the boost pot is a 100k lin, and R12 100k
BTW, the schematic can´t be verified, only have a look at the wrong Led-orientation (beside others).
