  • Mini 2x100W TDA8920BTH Audio Amplifier Board class D

    Anybody played around with one of these?

    2x100W TDA8920 +speaker protected Board class D BTL - eBay (item 200484848802 end time Jun-24-10 20:07:06 PDT)


    I just bought one - I don't know why other than a bout of ebay gotta have it.

    I am curious what size power transformer I'll need, since it allegedly will output 8 amps at full power.
    Do class D amps power supplies have to supply current like regular tube amp supplies?
    This may be destined for a subwoofer amp, or a small paperweight, I'm not sure yet.

    The seller got back with me and said something 8 A and above would be best. I guess that doubles my duh moment and I still haven't taken it out of the plastic.
