The manual and my board are correct. I checked the schematics and boards of a 7A15 which has lots of 151-0402-00 transistors. The order is definitively CBE (left to right, bottom view, flat face up). That would be TO92 order (A) in the cross reference page 9-5. The cross reference should have mentioned case TO92A then in stead of case TO92.
So I guess your Q320 was not mounted backward after all?
Yeah, the U530 was a typo. But, I was getting all 8's and 0's on all
