| SpeedRacer | Re: NFB -- where its tapped, & NFB resistor 47k is the value for the 50W heads, 100K is for the 100W.. The tap the -fb is taken from determines the amount of voltage that is fed back.. 50W into 4-ohms is a lot less voltage than 50W into 16-ohms. Tapping off the 16-ohm all else equal gives more -fb. |
