Scott Marine Radio
#2

I replaced the yellowed and shrunken dial glass with a new piece of clear plastic.  I need to figure out how to engrave the band numbers in the plastic to make it like the original.  The original was cracked, loose, and very yellowed since it had shrunk and broke out of the pins that held it in place.  LED's powered from the negative supply now back lights the  dial making it easier for me to read.  Compare it to the previous picture.  My "magic eye" tube, a military 1629, died so I had to use a 12 volt tube with the rest of the pins cut off to provide continuity in the series filament line to get the other tubes to light.  I have a NOS on order.  I've also ordered new electrolytic's, all 60 mfd at 250 volts, to stuff the cans even though there is no hum at this point.  I'll replace those and a couple of "dry electrolytic's that are bathtub style.  Voltage measurements show no leakage in the rest of the paper bathtub caps, so I'll wait a while before replacing those.

This radio performs very nicely.  Once I replace the filter caps, I'll re-align  to peak it's performance and align the dial a bit better.  It's not that far off, though.  I'll also get the 4" pm speaker re-coned since it occasionally buzzes. The cone is warped a bit.  Enjoyable project!
