Siemens 2000 16mm movie projector amps
 
   

  The Siemens 2000 projector was the most sold 16mm projector in Germany. Thousands of them were sold to schools or companies. Usually the projector was accompanied by a green speaker enclosure with L307 or L405 speaker.

  Forget the preamp section of these amps - very noisy and unlinear frequency response. Some power amps are good - some need mods to sound like hifi equipment. Some of them do not use feedback (or very low) and carry a lot of hum with them (not too disturbing with the original speakers, but with a good woofer or horn system ....).

Klangfilm Siemens 2000 smf V Sf Sf. projector tube amp EL41 PP EF40

EF40

EF40

EF40

  First version of these amps introduced in 1956. Rated at 10 watts with rare tubes. Capacitors need careful check (hum on most units). Better use the later EL84 PP version.

  Later version of the avove amp with magnetic sound facilities.

  Pretty rare amp.

 
Smf V 4b EL84 SE

  Introduced together with the above amp, this is my favourite one from this series. 5 watts of single ended output power. Bigger ouput transformer than in the later EF86 type. Better sound!

  Precurser to the 6.7 amp, but using EL41 output tubes. Good. Rare.

 
Sf V 6.4 EL84 SE

EF86

  Inferior to the EF40 version. Smaller output transformer. Needs proper modification (click here to see how to do this) to perform as Hifi amp.

  The best PP amp. Some units carry a T42 input transformer - very nice. Bad preamp section, but the power amp section is good. Very common unit. 

 
Sf V 6.6 EL95 PP EF86 ECF80

  Originally not seperable from the projector. This is why this unit is mostly found without top plate.
