Zeus

"Zeus" is named by the owner who commissioned me to make the amp. He wanted the more expensive 4U enclosure but with a silver face plate. So that's what he got. Inside is 1KW tranni and 80,000uf of 100V filter caps. The Holton amp modules are special in as much as they are 200W modules with upgraded dual die power FETs to produce 300/500W.

As usual a RFI/EFI power filter is included and a 240V speaker protection module. Amp weighs a ton and looks real pro. And what's more sounds excellent. Heavy as this amp delivers better than it looks. The owner and I are both happy with the result.

  • Hello,
    What did you use for the power supply?
    Did you use the Holton power supply controller or your own design?
    I am curious as I’m building one myself, but using the NXV 800L modules.
