Default Tube Amplifier Builder's Competition

I was wondering if any clubs in the Northwest USA had tube amp builders competitions. I would imagine that such an event would be judged by well known audio experts and that folks could enter, demo and get judged on their best builds.

Anything like that out there?

hi, I wish there were and maybe something could be done about starting one. I am the guy who's built the monoblock circlotrons with 3X3-6550s in the output stage and I think I'd be able to compete. I'm in the midwest though. plus, I would need to get the high impedance systems going for any demo, but sounds fine on my modified bose 901's wired in series, with two 18" subs tied in with high impedance low passes. Also have three ribbon tweeters per side, on top of the boses. A special set of 250ohm to 8ohm transformers could be made up for max power, but I'm going for an OTL topology, so raising speaker system impedance is the way to go...What have you got? I visited to washinton state area about 7 years ago and loved it.... If the whole event could be made totally trustworthy, with bonded personel working the contest, perhaps amps could be mailed in, and uncrated , judged, then re-shipped back to owners. They would have to be ear tested with matching or same speakers of course (with power,distortion and freq. sweep equip. as final testing)...with a small entry fee to defray costs of contest....perhaps the management personel of DIY could be such individuals..??...midmoe

hmm but there would be some issues as everything would be very subjective, cause im sure some people would just measure freq responce and distortion to give a verdict rather than listening to how musical the amp itself is. So i think some thing like what triode festival in europe has going on with their "shoot out" would work nicely but i dont want to fly to germany just to compete. A blind listening room with a 3rd party non competer handling set up and stuff and blind voting of the comunity. Something home bound in the US would be very nice. I am also unsure about the class system, as I have seen many an amp built by some no name talented person compare very well against big names, and again most of it is subjective again. Again of course no SS allowed (hahaha)
link to the triode fest shootout.

Anyone else have some input for this? I see the competition being in Seattle or Portland with someone who could loan some very high-end source, interconnects and speakers. The competition would be officiated by three judges who would not be able to see the equipment in play as the amps were rotated through...

The USA is big. If this is realistic, it should be somewhere more central so those in the northeast and midwest don't have so far to go. And it should be more of a full DIY audio festival w/ sub-areas, such as the speaker shootout, and the tube shootout, and the SS shootout. Get enough interested, we could rent a big room in vegas.. that's why that place exists.

I think it should be in Toronto, not as cool as Vegas, just closer to me.

I think it should be in my house, 'cause there's no way I'm even attempting to ship the Midlife Crises anywhere!

;-)

That's my thought, too. people would have to drive.
Imagine picking up your amp to waist height and dropping it on concrete. That much of a drop is basically guaranteed if you ship it.
Since we're all being selfish now, I vote for somewhere in Missouri.. it's literally the middle of the country, and then I won't have to drive far
