THAT PESKY MISPLACED C19!!
We all make mistakes... Sometimes they aren’t bad enough to
scrap a batch of PCBs and start over. This is one of those cases.
C19 needs to be hacked into place as it was accidently connected to
the V supply rather than the collector of Q5. Here’s how to get it in
place (see cover image too).
When placing
R27
leave the bottom leg proud from the board,
giving yourself enough bare metal to attach a wire.
Now you need to solder one leg of
C19
to
pin 3
of the
PRE
pot.
This is the sturdiest place it can attach to.
Now solder a wire to the free leg of
C19
, and attach the other end
to the proud leg of
R27
.
So what you’re actually doing is this...
C19
