I got a 330mm wide by 300mm deep mini dissipante. 4xMod-86, 200VA Antek transformer, and a Power 86 fit in there. Wiring will be somewhat challenging. Will have to mount the amp boards higher so that the back panel jacks are mounted above and below the amp modules.

Oh, fun. I'm guessing you went with the 2U to challenge yourself. In the 3U you could probably just stack the boards on the heat sinks.

I'm looking forward to seeing your build pictures.

Tom

I was originally only building stereo amps in the 2U chassis. That is much easier.


Nothing ever goes as planned.

And just like that Rev. 2.0 is born: Neurochrome Modulus-286: 65W (8Ω); 125W (4Ω) @ <-120dB THD Composite Amplifier Module

I expect to open up for pre-orders over the weekend. I'm waiting for one quote to trickle in before I can lock in the pricing, but I'm thinking $350-375 is realistic. I'll offer these to the early adopters at a significant discount as a thank you for your patience as manufacturing will take a bit. I expect the modules to be in stock by the end of November. At that time the intro pricing will end.

Tom,

The module looks nice and really compact. And I am sure it is not only about looks, but the well thought out engineering and design layout you have come up with to get top notch performance.

Thank you. Yeah, I rather like it. The final version will feature the same end brackets as the Modulus-686 (see attached) and an aluminum back plate. All you have to do is give it a think coat of thermal grease and bolt it to the heat sink.

In case you're looking for a deal on the new Modulus-286 Rev. 2.0 modules: I opened up for pre-orders this afternoon. The sale is on until 23.59 Mountain Time (GMT-7) on November 30th. Get yours here: Modulus-286: 125W composite amplifier achieving <-120dB THD

I do. You can find them as a "board option" for the Modulus-686: Modulus-686

Note that the brackets only fit the Modulus-186, Modulus-286 Rev. 2.0 (not the previous versions), and the Modulus-686. The 186 and 286R2 will come fully assembled, so you don't need to order the brackets separately for those.

Tom
