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).
Some people WRONGLY assume that a Pleasant Company neckstamp indicates a pre-Mattel doll. For instance, you could buy a Kaya doll today that has a Pleasant Company stamp on her neck, BUT she wasn't introduced until 2002 and has a side tag on her body that says American Girl.It is impossible to buy a pre Mattel Kaya because she didn't exist prior to 1998.olls made in the late 1990's have a tag sewn to the side of the cloth body which states: Made in China Exclusively for American Girl, Middleton, WI 53562. The majority of dolls made before 1998 do NOT have a body tag.
