Rhysh,
Any comments on why Jeff Rowland engineers decided to use the inverted arangement for the construction of this amplifier.
What is the preferred method of adjusting the bias? Do the remaining two chips need to be out of the circuit as you adjust the one.
I wish those folks would PAY so we can begin to play. This time around the project will be a work of art. Much learned along the way. More yet to learn.

I couldnt tell you, you are better off looking for more information from alex88.
All three chips are in the circuit whilst making ajustments, this is the way which it seems to be done.
some say that the inverted configuration sounds better but maybe that's a generalization.
I personally believe that it's the simplicity of this amp that makes it worthwhile.

The wiki page is backed up and in a database. For the people that are not going to pay up before the forum upgrade, that is just causing delays for everyone. You know who are are and so does everyone else as per wiki.
Hello rhysh
Just add 4 boards. Please inform if any additional mailing cost to my country at:

Payment will be sent tonigth.
Thanks a lot.

That is no problem.

Thanks Rhysh
What is PA150 output watts at 8 ohm load. I may want to try a non bridged version first.
Thanks again

And PA150 output to 4 Ohm is 150 Watt... Right?
My loudspeakers are in the 3 to 4 Ohm region, so I want to try the PA150 boards single ended...

Hello Rhysh
How to order 1 DRV134 board? Did I miss something? Thanks again

DRV134 boards are $5 each. They are to convert from SE to balanced.

Just paypal me $10. Shipping cost is free, i will bundle them with the other boards.
A note to everyone: Some people have not payed up. The names of these people are on the wiki. I will not order boards until everyone has paid.
