European Triode Festival, ETF 2017 - recap


Back home from the ETF which was a blast! Time for a recap.

Yet again this was a very well organised event. Bjorn and Karsten set the bar very high for the next year. But I am sure Tim and his team will pull off something very nice.

This years shootout was very interesting and comparing speakers is much easier at such an event since differences are quite audible. This was reflected in the votes which always showed clear preferences of the audience while in previous years it often was close to a tie.

So many very interesting contestants, some of them slabbed together juste a few days before the festival.

And well organised with exact measurements before the actual shootout and levelling of each participant for the same volume.

Since such a large room had to be filled, the contestants all used the bass of the main speaker as sub.

This main speaker was a collaboration between very different people and it is amazing what they achieved and  how well the different philosophies combined in this set up worked together.

Most notably the horn mathematics of Jean Michel Le Cleac'h who sadly passed away a few years ago. His legacy however is alive.

Also so many different construction styles in amplifiers in one place.

This always reminds me of an editorial Joe Roberts once wrote in Sound Practices.

Sometimes a project is $5 parts in a $5000 box, sometimes it is $5000 parts in a $5 box or $5 parts in a $5 box. But most of the time this simply doesn't matter.

It is great how all these different characters and minds come together at the ETF and have fun.

As in previous years Stephan brought his array of measurement equipment to give others a chance to check their amp or preamp and to help them to debug or complete their projects.

And one never gets tired to gaze at those glowing tubes:

And the interesting chats, music and relaxed atmosphere!

We had a great time together. Looking forward to meet you all again next year in France!

Best regards

Live from Denmark : ETF 2017, Part 13 - The Auction


Like every year the ETF ended yesterday night with the auction.

Morgan Jones ran the auction this year. The proceeds from the auction help to fund next years ETF.

The items are donated by participants. Before the auction starts the items are on display so you can check out what to hunt for later on:

Before the auction started the location of next years ETF was announced:

After the festival was hosted in Denmark for 3 years it now moves to France. Tim, Dominique, David, Jerome and Christian are the new organisers. A big thanks to this crew for taking up the challenge and for continuing the tradition. Then Morgan steps in and starts to auction off all the donated items.

Not only audio stuff is offered, but also things like fine port wine:

As every year the auction was great fun, Thanks a lot to Morgan for the show.

And a big, big thank you to the Danish team for yet another great festival. Sankt Helene was an excellent venue and they managed to continue the tradition of this very unique get together.

Looking forward to meet you all again in France next year

Best regards

This years shootout was about highly efficient speakers.

Here the contestants:

The contestants were all supported by the sub bass of the main system so they could fill the l,arfge room with sound.

In the first round pairs of contestants were listened to and the winner then went into the second round.

Source was a Revox R2R. Here some clips of the first rounds. Distortion in the audio is caused by overload of the mic.

Result of the first round:

The final round will be covered in an upcoming round

At last years ETF,  JC's presentation about distortion in guitar amps was very popular, so he expanded on the topic this year.

I captured most of the lecture on video, enjoy:

Thanks, JC for the great presentation!

Some impressions of the main system at this years ETF.

A collaboration of several people. An array of different amps drives the active speakers.

One of the amps made by Dave Slagle with transmitting style tubes and mercury vapour rectifiers. He carried over the amp in his luggage in pieces and it got inspected and taken apart by the TSA, hence the tape...

But he got it working again  no problem.

Here a video clip of the system playing. The distortion is caused by the camera mic being overloaded.

Best regards
