The Fine Things are Always Hand Made
When I bought my radio it was missing a couple of the coils and I found replacements. Recently there was an eBay auction for a set of coils and the person took very good pictures of the coils. I noticed a discrepancy between the ones pictured and mine. The 15-21 and the 21-27 were opposite for which had the red dot. I will include the picture I borrowed from eBay and the picture of mine. Which is correct?
The second set lying on the table scarf are mine.
Page 6 in the manual (in the Archive) shows some additional coil identification info.
It is not uncommon for the caps to come loose from the coils. There is a fair chance that the caps of the eBay set were switched when replaced on the coils.
OK, your 15-21 coils are backwards with the red dot. The red dot cap should be on the coil that has the single 4-turn winding. The cap without the red dot should be on the coil that has the enamel and cotton covered wires interwoven. Hope that makes sense!
