We believe this documentation to be free of any copy rights and/or errors, but if you know of any infringements or errors or alternate versions please contact us at mailto:[email protected] as soon as possible with this information. 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
