Thank you for your fine work. I needed to rewire a Teisco NB-4 and found you schematic very useful. I think there is an error, however, with regards to the diagram of rocker switch positions, and the circuits they activate. I believe the 'parallel' switch setting is actually the 'serial', and vice versa. The diagram shows the bottom of the rocker switch. With the lugs on the pickup side of the switch engaged, a series circuit results, and I believe this is opposite from what is shown at the bottom of the page 262. I mention this in hopes of correcing my misunderstanding if that is the case, or, improving your documentation, if that is helpful.
