Hi Have just finished a refurbish of a Bell and Howell Filmosound
16 mm 643 film projector, bit of a difficult refurbish but very worth while when the finished product is running.

Its all valve audio also exciter lamp feed oscillator, and HT rectifier.
This one has not had the main nylon drive gear changed as its fine at the moment, also it runs film very smoothly compared to some 16 mm projectors.

It has both optical audio and magnetic, which has a extra 2 transistor pre amp, my service book only covers the 641 and 642 so I have very little info on this section.
