Attention, A10K = 10KB = Log !
Un vendeur de chez R.A.M. à Paris chez qui je voulais acheter un potentiomètre de remplacement m'a expliqué la subtilité, et s'il ne m'a pas raconté de bêtises : la première notation est asiatique, la deuxième est occidentale.
C'est vrai que c'est la galère l'histoire des potards, perso j'avais trouvé ca :
Citation:
USA and Asia:
A = logarithmic (also called 'positive logarithmic', 'audio', 'log' or '+ log')
B = linear ('lin')
C = negative logarithmic (also called 'reverse log', 'rev log', 'reverse audio', or '- log')
Europe:
A = linear (lin)
B = logarithmic (also called 'positive logarithmic', 'audio', 'log' or '+ log')
Y = negative logarithmic (also called 'reverse log', 'rev log', 'reverse audio' or '- log')
Terms:
Mono = one potentiometer section, one axis
Stereo or Tandem= two potentiometer sections, one axis
Duplo or Concentric = two potentiometer sections, two axes
Stacked = multiple potentiometer sections, one or two axes
Switched = one or multiple potentiometer sections, one or two axes. With switch.
Source-Date codes:
Some pots have a multi-digit code (usually 6 or seven digits) printed on it used to identify the manufacturer and manufacturing date.
The first 3 digits on the pot identify the manufacturer. The other 3 or 4 digits identify the manufacturing date. In 3 digit dates code, the 1st digit is the last digit of the year. In 4 digits date codes, the 1st and 2nd digits are the last two digits of the year. The last two digits are always the
week of manufacture (01 to 52).
