boards arrived with my Trill - yah π (thanks again)
a couple of questions:
(assuming above schematic is unchanged)
a) I assume all caps are non-polarised
b) C11 &C18 - what values - 1n?
if not do you have a pcb schematic - as the capacitors are hard/impossible to read π
but if they are all 1nF, then its no issue π
c) voltage at top
it looks like (from top) -12v gnd + 12v, but there are 6 points...
so I use the ones with squares?
if so what are the holes without squares around for?
d) J1 pinout
I assume this is for L-/L+ R-/R+ in, and L-/L+ R-/R+ out... but I don't know which is which π
e) fitting to Pepper...
how would you recommend to adapt pepper to use this board.
f) opamp
I don't have any NE5532N (I think thats what shown above)
but I have some TL072CP, that are the same pinout.
of course, happy to go buy some NE5532N, just means I'll have to wait a week or so for them to turn up π
g) any other changes?
whilst I have Pepper taken apart, would you recommend any other changes?
e.g. you mentioned a different regulator, but from your graphs above that seem to have minimal impact
(if Im placing an order at mouser, may as well order other things i might need π )
thanks again for all your help
