Description
Based on the more sophisticated Model B4 (considered by most Czech tape recordists of the mid 1960s to be the best ever produced in their homeland), the B41 & B42 (pictured) were more spartan and much simpler machines.
Where the B4 featured three speeds, these were single speed, mono recorders (B41 half-track and B42 quarter-track). Missing too were the tape counter and super-imposition features.
This simplification of design and the fact that very large numbers of these recorders were produced led to a very low purchase price.
