Class D question

Discussion in 'Amps [BG]' started by greybeard125, Jan 10, 2014.

  1. Been playing my Fender TV15 and loving it so I decided to dig a little deeper. Got the schematics and pulled mine apart to learn as much as i could and got a big surprise.
    No fuse??? On the schematic or in my amp. Is the thermal limiter the only protection for this design. I'm an ole point to point tech and just started playing again so I'm scratching my head.

    Can someone "splain" this to me?? Seems like a flaw to me. No instant protection against spikes & such.

    A fuse is protection against excessive current flow, that's all.

    Fender is using B&O Icepower modules. They have fuses on them.

    Many Fender designs use fusible resistors as well.
