Some of us are wondering how SoD is doing ?

It has been suspiciously quiet on this thread lately.

We have a provisional output stage schematic, but are
reviewing the heat sink / chassis design.

I haven't followed this story, is the Pass Monster amp going to be published for DIY'ers?

That is the plan! Nelson will publish it with specs etc once it is completed. But this will be a slow moving project. we will drop updates and info as we get things solidly nailed down.

I think the general concesious is that the 6 prototype amp channels will be finished sometime mid next summer!

We have some basics down. Power supply schematic is finished, w are just waiting on the final parts list.

Basic chassis layouts are nearly finished and are just waiting on the final parts list to finalize the Power supply and Capacitor chassis layouts.

Preliminary Amp Chassis concept is in the works.

Is it just me, or are the capacitors in the picture of that Madrigal amp not connected to anything? And it's no wonder Madrigal amps cost so much, there's no efficient way to step-and-repeat that ridiculous cactus-shaped circuit board!

As for those power supplies you guys are building: holy crap! How are you gonna explain that to the department of homeland security?

PS Vishay now owns everybody. Dale, BC, Röderstein, Ford, Volvo, Bentley, Airbus, Gazprom, etc.

Didn't strike me so much as a bomb as a rail gun.

I take that as a promise, my current insane project fully occupies my ball book.
Most will need some time to find economy parts.
I just managed to acquire a quadruple of 5000VA/110V toroids, getting a large bunch of +170V caps will not be that easy.

Cant wait to see what the cooling arrangement will be.

Any reason why Casey reminds me of Clintwood Eastwood as
Josey Wales ?

OK, well the CES show is 6 days away!

Casey and I are planning on getting together at the show and hammer out some details on the mechanical aspects of the design.

things have slowed due to the holidays but we are still moving forward.

We have found the inductors are going to be harder to get then first thought. a company we are wroking with has come up with some preliminary figures for the 2mh 20 amp inductors! Imagine 2 inductors made from 6ga wire, 6" in diameter and weighing in around 20lbs each! and they will STILL be dissapating 35watts each in heat! so we are still exploring our option swith those....

If any of you will be at the CES show and would like to get together and Buy Casey and I Dinner or Drinks! SPEAK UP!!! hahahahah But seriously Folks, if your going to be at CES and would like to hang and chat audio. email me and lets see what we can do to put together a mini DIY/CES get together!
