Default RD Audio RD-3250v2

Wondering if anyone knows the value of this resistor that sits behind the speaker terminals ??

It got hot and cannot make the color bands out that well..

It measures 31.00 K on my meter but not sure if thats what its suppose to read..


Also does anyone know what caps i need they are the plastic rectangler caps and they are marked 6n6 J100 anyone know the value of them?

The resistance will likely be much lower (less than 10 ohms). Contact RD Audio for the value.

The cap (from the information you provided) is a 6.6nanoFarad (0.0066uF) 100v cap with a 5% tolerance.

Next question is theres a diode marked C10 5T that connects to the base of the A1275 drivers along with a 510 ohm resistor..

Does anyone happen to know what diodes i can replace them with or a part number?

Is the diode bad? I haven't run across a bad one in that circuit.

If it connects directly from the drain to the base of the driver for the same FET, it's not likely to be a standard or Zener diode. It's more likely to be a bi-directinal TVS. Post a photo of the component.
