Tube Box E – Kompakter Röhren-Phono-Vorverstärker mit diskretem Aufbau

Großer Röhrenklang im Miniaturformat

Mit der Tube Box E bringt Pro-Ject echten Röhrenklang in ein erstaunlich kompaktes Gehäuse. Dieser vollständig diskret aufgebaute Phono-Vorverstärker arbeitet ohne Operationsverstärker und setzt stattdessen auf zwei austauschbare ECC83-Röhren. Das Ergebnis: ein warm klingendes, musikalisches Phono-Signal, das deutlich über die Erwartungen an seine Preisklasse hinausgeht.

MM & MC-kompatibel – einfach anpassbar

Ob Moving Magnet oder Moving Coil – die Tube Box E ist flexibel einsetzbar. Sie bietet verschiedene Gain-Stufen, die bequem über die Frontplatte gewählt werden können. Weitere Einstellmöglichkeiten für Impedanz und Kapazität befinden sich auf der Unterseite – so lässt sich das Gerät präzise auf deinen Tonabnehmer abstimmen.

Subsonic-Filter & Doppel-Mono-Design

Ein abschaltbarer Subsonic-Filter (20 Hz @ 18 dB/Okt.) hilft bei der Eliminierung unerwünschter Rumpelgeräusche, während das Doppel-Mono-Layout für eine saubere Kanaltrennung sorgt. Das metallene Gehäuse schützt die empfindliche Röhrentechnik zuverlässig vor Einstreuungen – für ein ungetrübtes, hochwertiges Klangerlebnis.

Individuell anpassbar dank Tube Rolling

Die ECC83-Röhren sind nicht fest verlötet und können einfach getauscht werden. Das ermöglicht sogenanntes Tube Rolling – also das gezielte Anpassen der Klangcharakteristik durch alternative Röhrentypen. Perfekt für experimentierfreudige Vinyl-Fans!

Great book for learning about startup culture.
Format: Paperback, Format: Paperback
I had this book for a while did not have the chance to read as soon as I got it. Recently finished reading it and learned a lot of great things about startup terminology and how to be fast and how to iterate things in a right way, how to go deep in the problem. Identify pain points for the problem etc. Overall great teacher for anybody who wants to get grasp of a being in startup world.

Learning Faster, Failing Smarter
Format: Paperback
This book is truly amazing. Each chapter offers so much to learn. It helped me review what I’ve missed so far, anticipate future challenges, and prepare ways to reduce the chances of failure. It reminded me that failure is inevitable, but the speed of learning, adapting, and retrying makes all the difference. I learned that luck comes through action, ownership is everything, and true success lies in persistence and focus. The book also emphasizes solving real problems with humility, data, and continuous iteration. I’m truly grateful to have found this book — it changed the way I think about challenges and growth.

You NEED this book!!
Format: Kindle
If you are involved in a startup, or thinking about getting involved this is a must read. Jame's doesn't just rely on his own experience, he has been advising founders for years and does this with close relationships, not boardroom pontification. His blunt approach is balanced with his caring critiques. You can read dozens of books on startups and find out, when you actually are in one, how little applies to you. This is not that. Must read!!

Excellent book with a lot of solid advice
Format: Kindle
I thought this was an excellent book. It gave great advice that I found really helpful in thinking about and planning my startup, as many of the other comments have noted. The key ideas as far as I remember are that a) you should talk to as many potential users as you can and find out what their problems are, and b) be laser-focused on solving those problems instead of building what it is you want to build, because the thing you want to create might not be the thing that they want to buy. In fact I did just that; I talked with just one potential user and found that what I had thought would be their big problem wasn't a problem at all for them, and looking at some hard numbers as he advises, it isn't a problem for the industry as a whole, either. I had to go back and reformulate my approach. I now have a 100% better value proposition for them. Just two words of caution: 1) The book assumes that your startup is an app of some sort. Much of what he's talking about is therefore specific to the tech business. Mine isn't. Mine is a real product that people can hold in their hands. That wasn't a deal breaker by any means as most of the lessons in the book are still applicable to my product and what I'm doing. Still, it would've been nice of him to acknowledge that someone's start-up may be a lemonade stand or something material and concrete like that. 2) Is the vulger language necessary? I mean, English isn't like some other languages where there's an enormous difference between the way a language is written and the way it's spoken, but still, do we need so many obscenities in a book on business? It reads in some places like you're in a bar with a tech bro who's had a few drinks and is lambasting your approach to your business. I could've done without all the four-letter-words. But maybe that's just my generation.
