I have never seen any ads
or announcements for the model 711. What Columbia appeared to do
in 1928 was to increment the model number and make a very slight change
to the model 710. My guess is that the price was unchanged from
the 710, at $175.00. It is doubtful that many were made, since
everyone wanted an electric phonograph by this time. |
I think that the main difference between the 710 and the 711 lies in the motor board. The 710 had a wooden motor board, and the 711 has a metal one. This machine has a triple spring motor. |
When I purchased this machine, it was missing the grille. I just assumed I would not find one, and would end up making one. Believe it or not, I found one immediately from George Vollema at Great Lakes Antique Phonograph. I have completely restored this machine. |
