    Hi people,

    It's been few days my amp* buzzes when I stroke hard my preferred C chord ... which was painful to my ears and very annoying (when I think about 1 hour of the tech guy to have a closer look inside this old machinery).

    *1953 dynacord DA V/15

    And today, no buzzing ... Yeah great !
    The counterpart of the good news, is that my trusty pilot light has died after more than half a century of glorious radiant work. RIP.

    Now I have to change it for one new (which will live few years I guess). I ask myself few questions about how the world spins and about this in particular :

    1/ Is it normal that a pilot bulb which is close to death cause a buzz in the sound ?

    2/ I saw it's a 6.3V bayonet bulb. But no amper value on it and I found a great shop with offers of 150mA (1W) , 250mA (1.6W) , 300mA (2W)... that's a lot of 6.3V Bulbs !

    I presume the different values have an impact on the amount of light they'll produced. Shall I take care of the amper value or just taking one or the other without other consequences than +/- light & heat...

    What will be your choice ??

    (Here is the kind of thing)

    The ones that go in Fenders, #47, last 20000 hours.

    I guess they could cause noise if they flickered.

    Are there markings on the bulb or the base?

    Thanks Hammerhands ! Btw makes sense to add the minimum heat inside the box !

    T47’s for Fenders. A couple of dollars is all.
