    Hey everyone. I recently acquired a Crate amp and it's blown the pilot light and I'm looking for a new assembly, but I'm not sure what voltage or type to use. I've measured 20 volts on the lead to the circuit board. I've tried a 3 volt light, but it blew after a few minutes. So I tried a 24 volt light and assembly, but it wouldn't light up. Unfortunately Crate is out of business so I can't get any info. I also wonder if a resistor might be blown and I have too much voltage. Any thoughts or info would be appreciated. Thanks.

    If you let us know the model number then a schematic will show the type.
    It is probably a 6volt lamp working from the heater voltage that is sat at around 20vlts DC by design.

    It is an LED 12volt it states. Probably a vehicle 12volt LED indicator will work ... maybe.
    I would fit a standard LED J8 Screenshot 2020-09-10 at 22.03.38.png and a series resistor say 4k7 instead of R22
