Thanks again Javier (dohcvtec): A143====>Panasonic NTE2362 ===> (Digikey # 2SB1030ARACT-ND) (do not be fooled into believing its a NTE126...) A143: DTA143X(ST) , Silicon Pn P Darlington Transistor Rb=4k7 Ohm, Rbe=10k Ohm, Vceo=-50V, 0.1A, 0.3W Replacements i know: UNR411F, 2SA1654 or for the desperate, a home made ;) (i'm not responsible for damage) design: Pn P high speed switch like 2n3906 with the 4k7 and 10k resistors like in the datasheet's schematic: The 4k7 Ohm is serial with the base followed by the paralel 10k Ohm.
