The 1937 Sparton Triolian model 1867

This page is about Sparton's Triolian series of radios

For the 1937 model line, Sparton Pulled out ALL the Stops!
The first preview of the new models was held in Washington D.C. in the lobby of the Shoreham Hotel as mentioned on page 32 of the May 1936 issue of Radio Retailing.

Starting in July 1936, Sparton took a special Pullman rail car Show Room around the country to promote the new 1937 models!

The first mention of the Sparton Triolian 1867 was in the July 1936 issue of Radio Retailing. However, the cabinet described is not what came to the Retail market. It is described as being in a Gold Leather and Walnut cabinet. I don't believe this cabinet ever got beyond the prototype stage.

Sparton took a HUGE two page ad promoting the 1937 model line in the August 1936 issue of Radio Retailing. (click on image for larger version)

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!
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!
