Building the Audio Note Kit 1 SET amp...

Hi, Folks,
If anyone's interested, I've started a blog with lots of photos, documenting my ongoing build of the Audio Note Kit 1 300B SET amp. If you've ever thought of building any kit before and want to get a feel for what it's like, you're welcome to have a look!

Brian said that there are three great, American mysteries:

1) The JFK assassination;
2) the aliens of Roswell, New Mexico;
3) Steve's amp

Brian and Pete are going over the amp together: I should be hearing from them soon.

Well, for all of you (all 2 of you?) who have been on pins and needles to learn what was going on with my amp, here's what we know at last.

My build was on target - nothing wrong there.

Furthermore, Brian and Pete WERE able to replicate the distortion issue. This relieved my worst worry that they wouldn't be able to even reproduce the problem and we'd be back to square one.

The problem, it turns out, was with the output transformers. Brian and Pete have NEVER seen this issue in all the years they've been shipping and assembling these kits, but somehow or other these transformers had become magnetized and as a result weren't putting out full power. How this happened is even more of a mystery since these trannies are all very high quality and thoroughly tested before they ship! Brian is going to get these trannies back to go over them with his transformer manufacturer/designer to determine what happened to cause this very odd result. In the meantime, Brian is shipping two new transformers to Pete to install in the amp. So bottom line is that I should have a perfectly working Kit 1 in a week or so.

Let me again emphasize that Brian and Pete have provided superb support. And if the amp sounded great before, it should be really amazing with this issue sorted out.

Whew!
