Question About Fuse type LED AD/DC compatibility to audio gears

[animefreeks]

Hello AudioKarma

I have purchased a Fuse type LED and it states that it is compatible with AC / DC, when I tried to install it, first all is working fine, After a few days LED light does not light anymore, and even if I put in the original bulbs it does not light anymore.

Do I need to modify anything on the fuse type LED's to make it compatible with the amplifiers?

Does it has an effect if the Amplifier is using Direct current for the lights and installed with LED with Alternating Current capabilities?

Thank you and more power!!

Reads like you have a power supply problem, check for any AC voltage at the lamp socket, expect 8Vac.
The items have a smd resistor (180ohms?) and 3 LEDs in series, guessing that the first LED will act
as a half wave rectifier. Some of the better items include a seperate smd rectifier, eg,


Suggest check for AC voltage

Yeah, it sounds like you lost your dial light voltage. Check for other fuses.

Thank you for the information provided, is it possible to provide where can I buy those fuse type LED's?

in this case the one I bought is not the correct specs for the Amplifier....

Thank you will check the fuse's if they have been blown.


I am not sure where I read it or saw it, they remove the capacitor on the Fuse Type LED's to make it DC is this a correct information?

is it possible to provide where can I buy those fuse type LED's?

google "Marantz LED lamp 8V", plenty on ebay, eg, "ebay 5338722076" these are from bulgaria (via china). plenty of resellers in
US and ...

in this case the one I bought is not the correct specs for the Amplifier....

Your items will be suitable, appears you may have simply blown a fuse or the LED has failed.

There is an AK member that will have the correct LED’s he goes by DJwojo. He will have what you need.

Hello

Yep fuse is blown, on the Board it is indicated 4A fuse, the blown fuse is only 1A.

Should a 4A fuse can handle the LED bulbs.

Thank you El Rubio

I will check him
