  • For this "Soundmirror" BK-437 from Brush Development Co. you will find all 14 pages from SAMS Photoshop on model BK-442. BK-437 is the chassis only. The Soundmirrors BK-442 table unit and the BK-443P (P = portable) are the most important in ths line which SAMS reflects as BK-437, BK-437S, BK-439, BK-441, BK442 and BK-443P. A number of variations of the BK-443 table unit and the PK-443P portable are "-1" (50 cycle) units and the "S" (slow) units operating at one half the tape speed. 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.
