hey all,
back again with the parentheses boost from a couple weeks ago. everything’s working but the boost - no sound, LED turns on.
BS170 voltages:
D - 9.3 v (using a 9.6 v power supply)
S - 0
G - 0
i’ve measured resistor voltages as well and this is what i’ve found:
R32: 9.6v on one side, 9.3 on the other
R29: 9.3v on one side, 0 on the other
R30: 0 on both sides
R31: 0 on both sides
i’ve redone R29 and R31 and they’ve got the same problem as they did before - voltages haven’t changed. i’ve also checked all the values and they’re correct. thinking my next best option is to redo R30 because it seems like it might be open, but before i go any further i wanted to get some other opinions. board pics here. hope everyone’s enjoying the holidays
