Fisher PH-490
The Fisher PH-490 ghettoblaster was introduced in 1981. It's massive and heavy, at 31 inches long. The entire front face is covered by a nice aluminum faceplate surrounding nice-feeling knobs and switches. The tuner knob has a weighted flywheel, allowing you to spin it from one end to the other with just one flick of the wrist.
Replacement antennas can be purchased on Amazon from POBADY, they have one that is almost an exact match. It measures 140mm collapsed, 720mm extended. The tip is just a little bit smaller, but that's the only real difference.
The speakers include 8-inch woofers (part number 709600), rated for 8 ohms and 15 watts. And of course there are tweeters too. Inside the speaker cabinets, there is a metal plate for reinforcement, a foam pad for acoustic damping, and a small rear bass port. The amplifier consists of a pair of Sanyo LA4125T chips. The service manual (which can be purchased HERE) says its output power is 2x12.5W at 10% distortion. But the German advertisement shown below says it's 2x7.5W Sinus (RMS?). So who knows. Regardless, its sound quality is very good for an 80s boombox, and it's VERY loud. But the bass starts off pretty light, it doesn't wake up until you crank it up. The same is true for its sister model the PH-492, which is nearly identical except for different speaker grills.
