The 1937 Sparton Triolian model 1867
This page is about Sparton's Triolian series of radios
The 1867 Triolian was Sparton's last and probably best Triolian. The only feature lacking is variable bandwidth IF transformers. Why this valuable feature was left out is anyone's guess. Possibly for cost cutting reasons, but gee, this is the ultimate flagship model for Sparton? You gotta include the GOOD features of the previous version!
My 1867 Triolian is in pretty sorry shape. The cabinet is falling apart and delaminating, the dial is pretty messed up and a couple IF transformers have been replaced with smaller units. Otherwise, it is complete and I have plans to reproduce that beautiful mirror dial it is supposed to have.
It is quite the radio with a Bi-Amplified audio system. It uses a pair of 6L6G's pumping 20 watts into the 15" woofer and a single 6F6G providing 5 watts to the two 5" tweeters. Total, 25 watts of audio power!
It also has a volume expander circuit which was a feature in several 1937 Sparton models.
Along with the 1867, Sparton also kept the 1476 in the 1937 catalog. The 11 tube Nocturne was also kept in the 1937 catalog
There will be more to come as the project progresses
Thank you for reading!
UPDATE:
I have been working on reproducing the dial for this radio. So far it looks like a successful reproduction can be made. More info to come.
This is an experimental dial with a mirror etched by a laser engraving machine. The finished dial is still in the works, but at least this shows that it CAN be done!
