One thing I remember from the last batch is that you had several out-of-spec units. Do the machine assembled units have better (or worse?) tolerances than the hand assembled batch?
It was almost 100% this time. A couple were right on the border so I kept them aside to have a look at them, and to keep a few spare.
The problems in previous batches have been the 10ohm 0.1% resistors
So I'm not sure if it's just a different (non-dodgy) batch of resistors this time, or it's something in the assembly process. Too much heat in manual soldering perhaps? But why
only the 10R resistors?
Given that I had that horrible batch that time, I'm always suspicious of them now.
