Telefunken RA 100

Template:Nicht vorlagenkonform Device Type Integrated Amplifier Telefunken RA 100

Start of Sale 1981

General Description The RA100 is the simplest - but also by far the smallest - amplifier from the 1981 series, if you don't count the midi components. This was possible by packing the power amp part into a hybrid IC and using a toroid core transformer. Of course, a hybrid IC is nothing a high-end Hifi fan would want to see in an amp...

Features 2x40 Watts RMS, 2 pairs of speakers (clamps and DIN connectors), high-pass filter, mono/loudness switch.

Connectors Magnetic phono/Aux/Tuner/Tape (DIN only), 4 x speaker (DIN plugs resp. clamps)
