BELLARI PA253 Stereo power amp
Tuotenumero 1079142Compact stereo power amp with exceptional sound quality - 2x50 Watt
The PA253 is a stereo power amplifier. Connect your preferred input RCA or 3.5mm stereo. Connect a pair of speakers to the outputs. Adjust to your desired level.
The chassis is made in Salt Lake City, UT. The steel sheets are cut, bent, formed and finished all by US labor. After that process the steel is then powder coated to a high gloss red all done by US labor.
We silk-screen the chassis and assemble the PCB's at our Salt Lake City factory. We then flow solder the PCB's, send them to post flow assembly where we
add the fragile components soldering them in by hand. We test the PCB's then send them to mechanical assembly were the PA253 is completed and tested again. The boxes that we use are made in a facility just a few miles from us.
