UPDATE. I think you are definitely right. The answer is in the first couple a paragraphs of Tape Recorder magazine article I posted from 1963. It also shows the resistors to be 500ohm & 700ohm which is more in keeping with the measures I got. The diagrams are also the same as mine too.
Maybe it would be worth checking the connections as they recommend and re-soldering just in case there is a dry joint.
