Errata: Sunking

[madbean]

Okay, I done goofed. An error in the output section of the Sunking was pointed out to me by a fellow FSB member. Luckily, it is pretty minor and an easy fix. There are three resistors that need to be removed from the board, and put on the switch. Also, two wires will need to be moved to different pads due to the missing resistors. Attached below is a diagram on how to make the correction.

My sincere apologies on this oversight. While it is not a huge mistake, it is one that escaped me for some time, nonetheless. I have not compared the corrected version to the original, but I am currently finishing up the prototype for the revised Sunking board, so hopefully I can provide some insight on whether or not there is any difference, tone-wise.

I'm guessing the same mods need to be done to the single layer version over at FSB?

That one is already corrected with ver.2 in the Sunking thread. If you built ver.1.5 or before, then yes, make the correction.

Hi Brian,

I have the 2009 Mythical Unikorn version. Does that need to be modified?

Thanks!! Rowland

How does the change affect the sound?

Yep, you should make the same change on the MU.

The output will be slightly hotter and the buffer will sound better.
