PA-20 stereo power amplifier
The Xindak PA-20 is a stereo power amplifier with an entirely dual mono internal structure. It operates in Pura Classse A and is credited with 100 Watts per channel.
The voltage gain stage adopts a specially made input transformer for maximum sonic performance; the output stage is made up of no less than 48 high-power transistors mounted in parallel, capable of delivering an amount of current capable of driving any type of loudspeaker with authority.
The power supply section adopts a double toroidal transformer and is assisted by a filtering section, based on numerous filter capacitors, capable of supplying all the energy necessary to perfectly reproduce even the most excited musical passages.
The PA-20 stereo power amplifier features both unbalanced RCA inputs and balanced XLR inputs . The output terminals are the precious German top grade WBT-07 gold plated, 2 parallel groups for each channel, so as to be able to create bi-wire configurations with the speakers.
The chassis is characterized by special cooling fins with very high heat exchange, made of heavy and thick aluminum. This trick means that the Xindak PA-20 can actively dissipate the large amount of heat generated by operation in Pure Class A, being able to operate in conditions of perfect thermal stability
