The French Teppaz company made some very nice-looking portable record players and electronics from the 1930s until around the 1960s...? There's not much information about the company online, even though the company sold hundreds of thousands of units according to this ad. We'll take one in Versailles green!
Here's another potent portable, a Philips EL 3572 tape recorder. According to Reel-Reel.com it was made from 1959 to 1962 and could deliver a whopping 2.5 watts output.
This circa-1950s or 1960s Ampex 601 reel-to-reel was quite a step up from the Philips, as it was designed for professional use. Courtesy of Wikimedia Commons/Sverma.
We can't get enough of that 1970s look, as exemplified by this Kenwood KA-405 stereo integrated amplifier (actually, it was made from 1979 to 1981). It delivered 55 watts per channel into 8 ohms, and even offered a mic input for when the mood to sing along with the music might strike. Courtesy of Vintage Chief.com.
Well, this 1980s Pioneer P-D70 compact disc player...might not have won any design awards. We suppose they thought it looked futuristic at the time.
