Hello Calle

... as you know im burnproofed with BPA300 ... and since there lie about 24 LM3886 around here incl. some LF412ACN's they need to be placed somewhere nice ... that's why:

I'm interested too in 4 pair of pcb ...

BTW nice work !

Greetings

Hello all...

First, here is 2 pictures of a assambled board:

They have been playing daily at my home now since i got them and they do sound great, and works great! Heat is no problem, the servo-circuits keep each LM's dc-level to a minimum keeping them cool.

In fact I have a deliverance scheduled at 21 juli from a pcb-manufactor, 250 pcs. The differens from these boards is onboard regulators for the 15V, but mainly the layout is now non-inverting, instead of my current inverted once. This is to get the input-impedance to a higher level (47k). But, these 250 pcs is allready booked to a bunch of swedish forum-members. But if they work well then I will for shure order more boards and offer you guys.

Rendered image of board below:

So anyway, you'll have to wait a bit longer...

It looks like it is worth the wait... I will keep tuned-in.

Just to satisfy my curiosity: did you go any further with the 6-chip development?

Cheers!

Hello Calle,

Due of waiting ... would you share your gerbers or even eagle files of both verions here (with/without 15V supply) ?

Do you have a link to your swedish forum to get some more impression to your board ?

Would be very nice if you would / could share it

Thanks in advance
