嗱,我都未用過架! 都係睇書咋, 因為用係放大管陰極电阻, 电流大. 發熱高, 以免在高温下影响阻值.用鋁殼就 ...

師兄，架仔未生產水泥電阻前，美國佬、歐洲佬及牫太公都係用幾粒炭阻湊湊埋埋作為cathode R 用。構成今日嘅所謂靚聲名機，think about it !

建議上50W

Sorry, I am not sure I  understand  what are u trying to imply. Are u saying, 1/ cement resistor is not as good.. Or 2/ a combination of multi-resistors sound better, or 3/  hi power resistors are not necessary for good sound...

Have tried RS, they do have aluminum housed resistor. But somehow, could not find 750 ohm model...and they are not that expensive as expected . For a 20W model, somewhere around $20 to 30

Let me extract these statements from other Forum :

-- "Carbon Comp resistors induce distortion in a way our ears like."
-- "Use Carbon Comp's sparingly - only where your personal ears tell you that they make a difference. "
