I have now posted a users guide for the LM3886 kit on my website:
http://www.chipamp.com/docs/lm3886-manual.pdf
Sorry for the delay in getting this manual out.
If you have any farther questions, drop me an e-mail, and answer them for you, and work more material into the manual.

very nice manual. :up:
But why in 2.3 Chassis Considerations you are using metal bolt for transformer mounting? Maybe brass bold or plastic strips would be better for this purpose? |

This was more of an issue of what is most commonly available. Brass bolts might be better for this purpose if you find an easy source for them.

Well, it wouldn't make much difference would it or has somebody proved that brass bolts sound better? After all toroids have been mounted almost exclusively with normal standard steel bolts almost since the Jurassic period.
Great work Brian! |

| While I'm not going to enter the metaphysics of bolt material fray, both nylon and brass bolts and nuts are generally available in any real hardware store, in the plumbing supply sections. Its generally what is used for affixing toilet seats, bowls, etc.... |

Fixed. Thanks for pointing this out.

Also, keep in mind that the picture shows "what not to do", and is an example of how a shorted turn would occur. Using a plastic strap would avoid this problem, or proper rubber washer.
The shorted turn is a common problem, as this section is an attempt to avoid it.

| One way to avoid shorting condition, is using epoxy filled toroids, with a nut coming from the bottom. This type also allows more clearance, as the metal cap on top is not required. All Plitrons can be ordered this way now. |

Page 11 second last paragraph:
| quote: | | The fuse required will be dictated by the size of the transformer, due to the inrush current when power is first applied. A 2 amp slo-blo typically works fine for transformers around 220VA or less, while a 3 amp slo-blo fuse might be required if using a larger transformer. |
A question (not an answer): Isn't the inrush current determined by the size of the first cap in the power supply? |
