SIMA P-20 Preamplifier & W-200 Power Amplifier
|
|
The P-20 preamplifier and W-200 power amplifier were the very first
components manufactured by SIMA back in 1980. The P-20 included
an RIAA phono section for moving-magnet cartridges, the W-200
produced 100 watts per channel into 8 ohms and was bridgeable for
mono operation.
