Wow, that was quicker than I expected.
I'll stick with the second version though even if it's really tempting with the extra power. It's my first power amplifier so it might be good to have some spare cash for replacement parts if I manage to do something stupid.

Btw your build is starting to look really good!

Btw it's really looking good, the build I mean.

It has been finished for a ouple of months. It will be stripped out and put in bigger case for final version.

Want to sell that case?

[buzzforb]

Ill sell anything Got a 3/4" face plate and top for it as well. I can build one for about $200, so that's the way I usually go, although I have been tempted by the Store cases. Here is my last finished case.

Buzz - that is VERY sweet!

[mordikai]

Would it make any sense to use the 63v caps for the V3's and the 50v caps for the V2's? Would that even make a difference in there availability?

[buzzforb]

It does not help any., unfortunately.

How about everyone add which caps they want to the list.
T-UP vs T-HA.

Ill post the datasheets.

Buzzforb,

Very nice build. I wish I have your skill on metal work! I am with you that it is better to build the V3 is better as mono blocks. If I am going to use a chasis like yours, how should one hook up the 4 MOSFETs from each heatsink to the PCB (8 MOSFETs per block). The board will have to be hanging in the middle of the case with wires running to the heatsink on both side?

By the way, please let me know when should I sign up for the GB on the matched MOSFETs and diodes. Thanks!

Are you using TeaBags boards? Ill finish my monoblock using his boards this weekend. It should give you an idea of how to do it.ideal sinks would be flanged Conrad sinks. Would make it very easy.

Have not decided yet. I am leaning towards the board from the DIY store. Unfortunately, it is not ready yet. You are right, the Conrad sinks with a 90 degree flange would be perfect for the job. One doesn't have to bend the legs of the MOSFET to fit. Looking forward to see your monoblock.
