This is another item I found during my trip to Chile. It is a speaker box from a 1940s Premier 20 projector made by The Ampro Corporation from Chicago, IL. The company was founded in 1913 by Axel Monson. Since it was in bad shape, with the tolex/leatherette that covered the cabinet missing or falling apart in many places, I decided to strip it to reveal the wood. This is how it looks after lots of glueing, sanding and waxing. The speaker that came in it is a 12" AlNiCo 50W 16 Ohm Jensen P12N, a really nice vintage speaker that unfortunately got its cone damaged in some spots. I restored the cone with PVA glue and tissue paper and will test it as soon as I receive the amplifier I bought to make it a bluetooth speaker box. Hopefully it will sound good enough to avoid having it reconed or replaced.

Update on March 2017: The speaker was replaced by a vintage 1970s 150W 8 ohm guitar amp speaker, as the original was too damaged. I later sent the original Jensen speaker to be restored, replacing its coil and cone, now it is waiting for a new project.

The bluetooth box project became a guitar amplifier project. This box now has an internal solid state 100W mono amp, with one instrument input and also a jack for an auxiliary line level input.

    Beautiful restoration, sir! I have this same model....would you mind telling me, were you able to remove the front grill completely when sanding/finishing the cabinet? Mine seems permanently secured (?) Thanks and great work!
  12. mcheconi mcheconi, 1 year ago
    JMusic27, yes, I was able to remove the front grill from the cabinet. Mine was secured by the screws that hold the speaker. You must undo the nuts from the inside, cause the screws are fixed (welded?) to the front grill.
