SIMA W-2002 & W-2003 Stereo Power Amplifiers
|
The SIMA W-2002 and W-2003 Power Amplifiers produced 125 and 225 watts per
channel into 8 ohms respectively. Identical in appearance except for an
additional 2 inches of depth for the W-2003, both models were bridgeable
for mono operation and factory configurable for balanced operation. As well,
no coupling capacitors are used throughout the audio circuitry and the
power-supply toroidal transformers were custom manifactured for SIMA.
