I got another bit of cleaning in the Sender chassis done this morning, deep in the lower back section and was able to bring the Sender Tuning Selector Switch back from beneath its cover of oily soot. I was amazed to find the Switch Plate was marked with luminous green paint. I would have thought it was far too dark in that location for such paint to work, unless there is enough glow from the surrounding valve filaments to keep the paint active.
