Wave soldering is the best.... but you only have burn thouroughly with the solderig iron.

It's only an optical thing with the scanned pcb. These 18 vias are very much in the groundplane.

The pcb is soldered and a few parts are left. It's looking real good so far.

Oooh. I'm looking forward to the completed amp!

Ahh good. That said it should be fine anyway. As far as i remmeber there was a dip16amp made which used a coin for the heatsink/groundplane. So i don't think it's THAT critical to strongly and directly attached to the GND plane.

The PowerPad IC was rather easy to solder :nod:

1 Get a thin layer of fresh tin on the PowerPad

2 Solder all pins

3 Burn the PowerPad with 450 degrees! Works just fine!

What do you think? Isn't the pcb cute?

I have now listened to this amp and I must say that it is extremely transparent. The colouration is none.... I'm very pleased.

 

[doobooloo]

Very nice! I wish I could give it a listen too.

 

[yhmzzz]

So good!!
How about the sound of the amp?
Only transparent?

 

[peranders]

Indeed! Isn't that boring, no flavours added.

Well, flavour is the wrong analogy here.

It's more like, no clothes added. In that case it's very very exciting.

 

[peranders]

I have listened some more and I can't hear or see anything I dislike. I simply like this amp!

 

[doobooloo]

peranders, when is this board going to be available for a group buy?

 

[jamont]

The board looks very nice. I wonder:

1) Can it be adapted to 110V AC for use in the US?

2) Can suitable transformers be sourced in the US?

Sorry, but there will be no group buy because of non-existant interest but I have a couple of pcb's.
