The maximum measured output impedance was 0.16 ohms, at 20kHz into a 4 ohm load, this decreasing to less than 0.1 ohm at 1kHz. This is not unusually low for a solid-state amplifier, but low enough that any effect on the amplifier's frequency response with a real load will be small.
The History of American Girl Dolls and Pleasant Company and changes in Book Illustrations. Pleasant Company began in 1986 in Middleton, Wisconsin. The company was founded by Pleasant T. Rowland, a woman who used to be a teacher and a publisher of educational texts. Rowland sold Pleasant Company in 1998 to Mattel. Pleasant Company is now legally called American Girl. The first catalogue contained only 3 historical dolls, whereas now there are 10 (not counting the new addition of the best friends dolls).
In 1958, it was sold to Dixie Products, a small stove company of Cleveland, Tennessee, after selling off a few underperforming divisions of Magic Chef. By 1986, the company had become the 249th largest industrial company in the nation and it was sold to Maytag.
