VERSION 0.1a
NEVE BA283 AMPLIFIER BOARD INFO SHEET

THIS DOCUMENT IS INTENDED AS AN AID TO SERVICE TECHNICIANS
TO MAINTAIN SERVICE AND REPAIR A PRODUCT THAT HAS BEEN
OUT OF REGULAR PRODUCTION FOR MORE THAN 15 YEARS.

THE BA283 AMPLIFIER PCB CAME IN A NUMBER OF VERSION
DECODE INFO FOR THE VARIOUS VERSIONS
B = Board or PCB assembly
A = Amplifier
283 = the three digit part number designation for the assembly

VERSIONS: note that most version suffixes here have two letters and these happen to indicate
the edge card pin numbers of the portion of the circuit board that is "stuffed" and there is a third "A"
letter designation added to those versions where the TO-3 output transistor is remoted off actual card
assembly.


      BA283AV = fully populated with both a pre or "gain" amplifier and an output amplifier
      BA283AVA = BA283AV with remoted TO-3 output transistor TR3
      BA283AM = 1/2 populated with only an output amplifier and NO pre or "gain" amplifier
      BA283AMA = BA283AM with remoted TO-3 output transistor TR3
      BA283NV = 1/2 populated with only a pre or "gain" amplifier and NO output amplifier
      BA283S = don't see these often but appears nearly identical to BA283AM

      The most common version would be BA283AM
      all BA283 boards have pads and traces such that they can be fully
      stuffed and converted to BA283AV
