Burning Amp is Sunday at the Firehouse at Fort Mason on the
waterfront in San Francisco at 10 am.
Santa will be driving down in an F250 loaded with goodies to give
away - power transformers, knobs, pots, transistors, speaker
drivers and other stuff for all you good little DIYers.

That sounds like fun. Too bad I don't live closer--this goes down as a "must do" on my retirement list.
I'm driving up to the city now! See you guys there. -David
P.S. David's been a very good DIY boy this year Santa.

My web clock says it's 7.55pm in SF. It's about 8am here !
So you guys are still busy but reached almost the end. You must have had a great time and be totally exhausted.
We'll give you time to recover , put your thoughts in order and then start giving us pictures and text about what really took place !
Sy will be off of course. Have a safe trip.
Jan and Magura , are you guys also leaving right away ? You will give us your 'European' view point of course (?).
Cheers,
Ashok.

WOW What an event!
It was a realy pleasure to finally meet in person many of the folks I've had the joy of working with on-line.
Choky, your presents was missed... maybe next year.
Nelson could have started a surplus store with all the tables overflowing with DIY parts. THANK YOU Nelson for the nice heatsinks, IRF240's, and a handful of Lovoltechs!
Everyone walked away with some cool stuff, exchange of design ideas and experiences, socalize and build friendships.
There are to many cool design topologies for amps and speakers for a DIY guy like me build them all. This was truely great to have a chance to experience different systems from large box speakers to low cost to expensive full range drivers.
My hat's off to the highschool student who built the full range drivers for under $60 a pair, they were actually one of the best speakers demonstrated!
Way cool.
Thank you to the organizers, Thank you to my new friends, and thank you Nelson for so wonderfully and generously sharing your engineering insights!

An X-mas gift also for the guys who can't attend the burning . . .!
Thanks

I am really bummed out that I missed this. I had a family emergency come up and had to take care of my son.
I am building two of Nelson's designs and could have REALLY used a couple of transformers, heatsinks, and the lovoltech's. What a really nice thing for him to do.
I wouldn't have missed this for anything, I had everything packed up and ready to go to. Of course you never anticipate your son being sick and needing to go to the hospital. Oh well, maybe next time...
If anyone has a transformer or two that they got from Nelson that they would be willing to sell, Please e-mail me. I would be forever in your debt if so. 🙂

I presume that now is everything OK with your son ; 🙂
besides that (and that's most important) , just one thought - it will be blasphemy to sell gift from Papa ; pass it further as gift - right thing, but selling it..... naah......
give a kiss to your son , and feel happy
Selling will just be wrong. But when I left, there were still a couple huge 23-0-23 25A transformers that nobody picked up because they were like 40lbs each. Maybe you can email Nelson and see if you can use one for a monster amp.
Huh! I can lift 40 pounds with one arm. I happen to know this because my daughter weighs about that. You guys need to work out more.
My problem is that I'm on the wrong side of the continent and my arm's not long enough.
Glad you guys had a good time.
(I still hate you...)

P.S.: Somebody's Flickr pictures are labeled Burning Amp 08...did I manage to sleep through an entire year?

The Burning Amp was a great and successful event. I have already posted my general comments and thanks to the organizers and other attendees over in the "Everything Else" section. But I thought I would add a few specific comments here about the great Santa Claus caper - which I believe will go down as one of the great DIY stories and which will be re-told over and over.
First off - it was utterly overwhelming. Nelson and Colin filled the bed of their Ford F250 with stuff. The pile was jammed in and extended almost a foot above the sides of the bed in places. Nelson even had to put the truck into "tow mode" to negotiate one of the hills in the city because there was so much stuff in the back. There were thousands of transistors. I recall one sealed Digikey bag containing maybe ten tubes of 50 each IRF9610's, a basketball sized bag of MJ15022's and another of MJ15003's. Nelson was wandering about with tubes of Lovoltech JFET's saying to people "You want some?" and if they said yes he would pour about a dozen into their open hand. There were literally hundreds of speaker drivers, including some very serious ones such as 3 or 4 pairs of Fostex FE208's that were raffled off. Many of the drivers were in unopened PartsExpress cartons. There were dozens of 1KVA and 2KVA toroids, and a whole bunch of 30V-0-30V toroids suitable for pre-amps and crossovers. There were at least a dozen of what appeared to be X150 heatsinks, some with transistors still attached. There were hundreds of old Threshold knobs that Colin was stuffing by handfuls into peoples swag bags as he put it "like Halloween candy". At 7 pm there was still stuff left in spite of almost 100 DIY'ers staggering off with arm loads all day long. I recall four to six Aleph 1.2 transformers still lying there unclaimed as I walked out the door.
Nelson got up briefly after Variac started the festivities and told everyone that he had promised his wife that none of this stuff would be coming home. So everyone worked really hard to make that a reality.
Nelson and Colin made a whole lot of people very happy and deserve a huge vote of thanks from us all for their generosity and graciousness. They really added something very special to this event.
Ya shoulda been there!

Yes, my son is okay now. Thanks for asking.
I could really use a couple of those 23-0-23 transformers and could also use a couple around 30-0-30 to 45-0-45.
I know selling would be kind of taboo, but I just really need them and would be willing to pay for someone's trouble.
With a new baby and my wife not working now, I have to watch my expenditures. It would have been like a little piece of heaven to get there and find out he was giving away some of the more "expensive" parts that I need to finish my amp/preamps.
Oh well, what can I do now but ask for the generosity of others...
Thanks,
Donovan

Just for the record, they were given away on a "pick a number
between 1 and 100" basis.
