Integrated Amplifier
1981
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.
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.
Magnetic phono/Aux/Monitor (DIN and Cinch), Tuner/Tape (DIN only), 4 x speaker (DIN plugs resp. clamps)

none known, except from the usual problems with scratching pots...I once had an RA 200 with an overvoltage damage, but of course that's not a 'typical' defect...
