In the Oakley/Proudfoot reference book "His Master's Gramophone" it's mentioned that the acoustic model 1 automatic was offered as an electrically amplified Model 15. Many of these originated as Model 1 that had been returned to the factory and then converted to Model 15.OrthoFan wrote: Fri Jan 06, 2023 10:53 amAccording to what Carsten Fischer posted on myvintagetv, the electrically amplified model would have had a built-in amplifier --epigramophone wrote: Fri Jan 06, 2023 10:40 am ...As for electrical amplification, the pictures show that the machine is fitted with an electric pickup head instead of a soundbox.

In late 1929 the Model 1 changer was offered as a electrically amplified Gramophone with a 4 vacuum tube amplifier and an electrodynamic speaker at a price of £ 200 and over depending on options selected.

Hopefully, the seller can clarify whether this is an acoustic model that has been modified, or whether it was factory equipped for electrical amplification.

The Ebay photos show some service notes mentioning the amplifier features, and the main photo shows an extra panel on the lower right side of the cabinet, possibly part of the amplification system. The electric pickup and non-tapering tone arm are other features of the Model 15.
I'd be all over this if it were stateside!
