@UKToecutter:
Maybe it would be the best to make a list of all the guys who would like to have PCB's?
cheers,
matthias
Matthias,
I already have.
Please see my signature. There is a link to a list
oops, ok... sorry 😉
maybe I add some more in the next few days! 🙂

Heatsinks: 7000 series - 7200HS

Wow they come 12 inchs tall ( 300MM) ... Jacco won't like that ... 😛
Do the math , it cost more to "build" 2 chassis than one, no matter which way you slice it . Here we can buy used exotica for 2K, so guess what spending 2 K for DIY does not make much sense.
Precisely, this will keep going around and around , i guess most here have never had a 100 watt class-a amp , it's monster size, monster heat , monster consumption.
Whats the cost on those sinks .... ?
You mean more convenient, Hard to make room or justify 4 mono chassis plus cost...
does it? when the stereo amp must be 4x taller? thats twice as much heatsinks as for 2 monoblocks. and the heatsinks are the most expensive part of the chassis. only topp and bottom plates that will be more expensive on monoblocks. and thats about 30$.
5.5 m/s air velocity.
Reduce it to 2m/s and you're scot(t)-free (t = including AndrewT).
increase it and you can dry your hairs while listening to finest music! 😀
I am a big fan of the idea of separating the output boards and input boards. This would allow for people to make the standard SE build, mono-blocks and balanced cleanly. It sounds like there are a number of people (myself included) who are looking to do balanced builds, and a separate input board could be made to support a balanced option (probably would only need a few jumper locations). It also makes building mono-blocks more straight forward as well.
Separating the input and output boards would provide the maximum flexibility, at the expense of a little added cost. In the scheme of things, the added cost for the PCB's would be pretty insignificant.
My 2 cents.
I agree, and allow for 2,3,4 outputs possibly - in an ideal world of roll your own need PCB.
OK chaps

very nice Andy.
Now the voting for what GB to do can begin 😀😀😀
GB?
GB = Group Buy
Those boards look nice.
Why are the wire connections between the front end board and the output board not on the same edge of the output board?

They are.
I assumed that people would want to mount the boards with the MOSFETS the same way up. Therefore spin one of those boards through 180 degrees.
