1960 Telefunken Magnetophon KL 75/15
Back to gallerySpecifications


The KL 75/15 was a modified version of the KL 75.

Among the improvements were an increase of reel size to 5¾" (15 cm, hence the "15" addition to the model number), the addition of a tone control (on later versions0 and a horizontal magic bar level indicator to replace the magic eye.

As was the case for the KL 75, a "K" model was produced with carry-case, amplifier and speaker, and a "T" model without the carry case and speaker but with the amplifier.

The specifications were much the same as for the KL 75 but the price for the "K" model was substantially reduced.
