Jan,
It looks great, you are an artist. Any rough idea of time frame for board availability?
I will save up for the transistors.

Does the lack of comments meen, that I can finish the project and publish the Gerber-files etc. ???

 

[Upupa Epops]

Go on Jan, guys are waiting.

 

[Jan Dupont]

Thanks Pavel

I will keep you all informed

Just a quick thought on the silkscreen, I always prefer the component designations next to the components rather than underneath. It just makes fault finding, (and I do a lot of that on my projects ), a little easier on completed boards.

So...
When do you think the PCB group buy will be running? (have i missed anything in another section?)...
I'm actually thinking of (shock) making a 5 channel version of this amp for home theater!!! I have a funny feeling though, realistically, if we want the 50w rms into class A from each monoblock (5 of them) do i need 5 1000va transformers? (torroids)?... That is a "stupid" amount of power even by my standards!!! (only reason i ask this is before i saw someone mention a 1kva transformer per channel, if this is not the case, please correct me!!!)
I'm definately liking this GB! I've heard this amp a long time ago and i remembered it was very very nice!
Thanks
Aaron
