Inductor Comparison Table
¿Es posible comprar un conjunto de RSP?
Hola, aprecio sus esfuerzos en un gran apoyo para la calidad del amplificador buenas patatas fritas en vez de simplemente cargando las opciones más baratas en su tableros, como muchos en el mundo hacer! Me gustaría comprar uno de sus diseños algún día.
Is it possible to buy this amp?
Bare (unpopulated) PCBs are available together with an assembly book and BOM.
what’s your suggestion for selecting “the right” coils for the output filter of the amp?
in one design you have the coilcraft ver2923 series with flat wires in it. in this version you have coils from würth elektronik in it.
do you have experience about THD N vs. flat wire or standard wire coils?
The flat wire inductors tested, performed all better than any other inductors, especially molded ones. I added a comparison table to the blog.
very very cool.
i have been looking for a 4 channel purepath amplifier pcb /kit to connect to my freedsp.
what kind of power supply works well?
i like to use multiple 2200uf 10000 hour electrolytic capaciator for amplifier power where i can. works well on lm3886.
would appreciate if you let me know how to buy/make your stuff.
Gracias,
p
