The Talking Machine Forum — For All Antique Phonographs & Recordings

I wonder if anyone knows when these sound-boxes were first sold ?

Thank you very much as always for any information you can provide.

1930's, if this Japanese website is to be relied on :

Thank you very much epigramophone.

So, the electrix sound-box was introduced at the same time as the electrix gramophone presumably.

Very interesting.
