Vietnam Audio Visual Network () is organizing their annual contest for DIY high power tube amplifier. The location for this year contest is Nha Trang.

They will have blind tests and the judges will tell which amplifier is the best, second and third. This forum has some main contests annually for speakers, amplifiers,... The location will changed every year through out Vietnam.
I think some people in this site will be interested in joining it.

- Name of contest: Sumo Contest 2014
- Time: 13h30 Sat, Dec 6, 2014
- Venue: ballroom, Yasaka hotel
Address: 18 Tran Phu St., Nha Trang
- Open for everyone

Please feel free to come there and make friend with them. I think it's always interesting to have new friends who have the same hobbies or taste of living.

Unless they speak technical Vietnamese, Sumo Contest 2014 might have limited interest to Foreigners. I went to one a year or two ago and was heartening to see the VN interest in electronics, particularly given the sad state of technical instruction in the schools.聽

Perhaps someone could design an amp using a pair of 807 valves/tubes - still around after all these years.

For Foreigner computer enthusiasts, there is a PIC VietNam Group < >. It will require heavy use of Google Translate to understand the web site.

There are other Vietnamese/English bilingual electronics sites, too.

This site and contest is for people who enjoy music & sound systems. Totally different from PIC.
The story of the contest: Vietnamese people always have to buy amplifiers, speakers,... from other countries for their systems. Some of them are good at electronics, technique,... They wanna create some made-in-VN amplifiers, speakers. They are learning and trying to reach the world's standard.
In the end of the day, it's all about entertainment, not about computer, laptop, software, hardwares,... or things like in the website you provided.

I think I know the difference between tube/valve systems and integrated circuits - the former glow in the dark and the latter don't; the former use lethal voltages and latter don't.

Again, the Sumo Contest, and their web site, needs and understanding of Vietnamese to appreciate the finer points whereas another VNese web site - for PICs has an English language component. Likely people having an interest in amps would also have an interest in other aspects of electronics.

I'm amazed 807s are still available. I assumed they've been consigned to the dustbin of old technology a long time ago. Ho hum, I hear most of the US isn't onto LED lighting yet; amazing such a rich and technologically advanced country is so behind the times.

The OP is trying to promote a little national pride in the electronics field, but I don't see her having much hope of getting far.
The idea of locally produced, smooth sounding amps is very nice, but you have fat chance of competing with the big corporations for the general market, or the smaller, specialised manufacturers at the high end.

Using bottles gives a nice smooth sound, but such as Denon easily match that with their mid range amps.
Nice idea, but doomed to fail.
For the rest of us prols, it's a little tranny radio or a basic system, consumer facts that destroy any real hope of this event working to produce local manufacturers.

Still, might be fun for those of us who enjoy jiggerypokery with a soldering iron.

Good luck to the OP and the competition, have fun.

In fact, I don't know much about the contest or technical things.

I joined the forum because I love music and movies. I translate movies' subtitles for them (any movies don't have Vietnamese sub yet).
I'm almost the only female member of the site.

What I was trying to do is to introduce to expats who are interested in vinyl, music, audio systems, movies, projectors, screen, blue-ray or HD movies, etc. cause I saw some posts related to those things like where to buy/download... I don't introduce the site cause it's not in English. I thought the competition might be interesting to some people and it's definitely different from talking in person to visiting a site. Maybe I'm wrong.

The web site is quite readable using Google translate. Must be useful - I bookmarked it.

You were not wrong.
There are still vinyl junkies out there, as there are people who like to stay warm with valve heat as they don't use their Android phone and headphones to listen to Justa Beaver or other crap, manufactured celebs.
