Now I understand.Well it's not quite robot-tidy, but I do like how these turned out.
When you put lots of holes in a straight line like this, it's easy to spot the "drift", even tiny fractions of it.
I spend way too much time on goofy stuff like this... and nobody's ever going to see it, on the bottom of the amp.
Thanks Dennis. I don't think this amp will need any extra holes on the top for "exhaust", though the tube socket is recessed in such a way that it will allow for a little airflow through the top of the chassis. With the tubes and transformers on top of and outside the chassis, these resistors are about the only things inside that might generate enough heat to need a bit more ventilation. Today's bit of drilling (108 holes, hah!!) ought to take care of that.Nice work Nate. You'd need a straight edge it see any of those holes are off. Do you have holes on top for exaust?
