    PAS 2/3: Making a connector strip from a copper PCB

    Post by jerdobi on Sun Jun 20, 2010 10:34 pm

    I replaced the stock connector strip with a custom one I made from a copper clad circuit board. I fabricated using a image transfer method using Teckniks transfer paper (see link for HowTo). Just create the board and order some of the RCA connectors from Digikey or Mouser.

    Here's the PDF Image File link to the PDF to the images you need.

    I made an I/O PCB similar to this. But, it looks like your main preamp out ground plane is separated from the tape out ground plane, correct? As I have looked at the original schematic and made continuity measurements on some original PAS samples I have, I believe that the main preamp output ground and the tape output ground are exactly the same point, with the 10-ohm resistor between the input grounds and the ground shared by the outputs.

    if anyone is interested, I've sold dozens of upgraded PAS3 and PAT4 I-O PCBs for using gold RCA jacks and wider spacing than original, bare PCB $40 or with all new jacks $65

    Is the PAS2 different than PAS3?

    The circuit of the PAS2 I'm working on would require the division to be between the Special and AM/FM inputs on one side and between Tape-in and Tape-out on the other. This is different from the board layout and the described circuit in the followup posting.
