B&O Moving Coil stepup transformer.
Type: U25/10 4068
The B&O MC stepup transformer is not known to many people and there is a good reason. B&O never produced MC cartridges and B&O never produced a transformer which they called MC stepup transformer.
But B&O have produced many stepup transformers for microphones. Really high-quality transformers like the Swedish Lundal transformers.
The B&O microphone transformers can be used as a Moving Coil stepup transformer and with an excellent sound.
The stepup specification are:
1:16
1:8
This can be set by jumpers.
The setup transformer is of course for MC cartridges with medium to high output like a some of the Ortofon cartridges.
Where can you find these transformers?
They are standard in all Beolab 5000 amplifiers of 1967.
