I just acquired a really interesting late 50's tube radio in good working condition - a Sferics SF-1.
I have attempted to obtain info. on the web but there is very little written about it and it appears few have been sold (on Ebay, etc.). I know it is from a small (short-lived) San Antonio radio co. and that it is a weather alert radio.
It doesn't even seem to be included in the large vintage radio collections chronicled on sites like radio attic and others - curious as to why.
If anyone has any info., please let me know.
Thanks.
