Telefunken RA 200

Template:Nicht vorlagenkonform Telefunken RA200

Device Type Integrated Amplifier

Start of Sale 1981

General Description The RA 200 was Telefunken's offering in the 1981 generation when you wanted something better than the RA100. It features more inputs (Cinch sockets for monitor, phono, and aux), a tape-to-tape copying function and a discrete, truly impressive power amp section with a liquid cooling system - see below.

Note that - like in the RR 200 - two sorts of mains transformers were used in the RA 200 that look very different. They are exchangeable, however.

Features 2x70 Watts RMS, 2 pairs of speakers (clamps and DIN connectors), low/high-pass filter, mono/loudness switch, pak level indicators with switchable range, monitor switch, tape-to-tape copying.

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