Thanks for the improvements and for making it a little easier.

It doesn't look like you ran into any show stopper issues with the test build.

Cheers!

Yes!

With the exception of one cold solder joint (working too late into the night ...) the new boards came right up.

I have been listening to it intently for the last week. All is well.

Thanks again to Douglas Self and Jan Didden for making this available to the DIY community.

PJN,
i believe it is Walnut. My Brother gave it to me a while back. As for the Printing, go to
Waterslide Decal Paper, Image, Transfer Paper, Iron On, Decals. Black on the dark wood is kinda hard to read from a distance but looks COOL to me. Had to get the wife (a typesetter by trade) to re-do the template for the correct size of the front panel so everything aligned up properly.

Default Using less voltage ?

Hi !

I already have a very good +/-15 Volts linear PSU.
Is there any drawback in using +/-15V,
instead of the +/-17 Volts recommended in the documentation ?

Thanks a lot ......

JM

(17V is the maximum voltage acceptable according to LM4562's datasheet)
