☑ 100k Nfb Resistor

The bass pa etc retained the original nfb setup even though there are exceptions. It looks like i need to unsolder one side of my nfb resistor tonight to check if my primaries are reversed.

Typically this depends on if you have a 50 watter or 100 watter.

100k nfb resistor. The higher voltage 4 ohm tap increases nfb voltage by 41 but employing a 100k nfb resistor cuts the nfb voltage by 39. You can add a 100k to 330k resistor in series with a bright cap to reduce the amount or volume of high frequency signal passing through it. 100k 100k ohm resistor colour code.

The 50 watt marshall amps with their 100k negative feedback nfb resistor tapped at the 4 ohm speaker jack get a little less nfb voltage than the 5f6 a bassman which uses a 2 ohm tap and 56k nfb resistor. The 100k resistor seems to begin appearing around 70 again lead amps only. Hi all reading through aikens website it sounds like it makes no difference what resistor combo you use for the voltage divider for the nfb as long as the voltage reduction is the same.

To bypass a volume or gain pot with a bright cap you connect the caps two leads to the pots input and output terminals as shown above. 4 band colour code system. 50 watters have a 47k on the 8 ohm tap and 100 watters have the 100k on the 4 ohm tap.

Resistor colour code standard resistor values ohms law resistors in parallel resistors in series. Brown black yellow gold. But why the 820r vs 100k big difference between the fender and marshall.

Hey there brothers. Will changing the 27k nfb resistor to 100k give the amp more gain. Heres a volume pot bright cap calculator.
