Also other machines of this series under model number BK-439 and BK-441 are table models which vary from the BK-442 only in the combination of speaker and output transformer. From the standard line of Soundmirrors there are units furnished capable of operating on 50 cycles with 110, 150, 220 or 250 volt - carrying -1 at the end of model number. Slow speed models are for instance BK-443-PS - or BK-443-PS-1 etc.
