Sealed in cellophane with a red tape.

These tubes were made more than half a century ago, and they have an S in the suffix. At that time it meant a lot more than it does today, today suffixes are just a marketing trick. It used to mean a lot more - careful testing and selecting from huge batches and checking of many parameters. That's exactly why I don't accept any returns. Returns are simply not possible. If Telefunken is behind those tubes marked with an S and sealed with a red tape, I can offer nothing more in terms of warranty.



As is, what you see is what you get. No returns please.






I collect tubes and tube gear for more then 35 years and I start to sell recently, please be sure to check my other items and visit my storeΒ and my page for more rare NOS tubes and parts.

I have more than 250000 NOS tubes in stock and just small part is listed here, if you are interested in any specific tube or part, please send me message.

If you buy any item on ebay from me and for if you are not fully satisfied for any reason or have any complains, please send me message before leaving negative or neutral feedback or opening a case. I really do care about your satisfaction and I’ll do my best to solve any kind of problem.

Essential reading for PowerPoint presenters.
Format: Paperback, Format: Paperback
Cliff shows details how to improve our PowerPoint presentations. He gives concrete and simple steps to transform a message into a targeted presentation. All of us have suffered from presenters who went over their allotted time because they had vital information to give us, yet we still didn't know their main point. Many have seen slide decks burdened with dozens of bullet points. Did the volume of points yield more clarity or did they dull our ability to focus on the message? Probably not. Read Cliff's book. Follow his method and you'll be a more effective presenter.

Useful with some scientific corroboration
Format: Paperback
Worth it as a primer to slide content and how it inter-relates to the delivery when giving a presentation. Very slightly laboured, like most TV documentaries nowadays - you feel they could move a bit faster (...yeah we got it the first time).

Simple and streamlined to meet anyone's needs
Format: Paperback
This book rocks! It provide a simple and structured way to define, develop and deliver a "Kick Ass" presentation that you can project or just use from the podium. It bring the audio and visual together to compliment a story to be shared. It has taken the hassel factor out of designing a presentation for anyone on any subject. Thank you!

Lasting value but degraded presentation
Format: Paperback
I've been a BBP fan since the first edition in 2005. The second edition in 2007 was a significant update and refinement. The latest, 2011 edition, is not worth buying if you already have the second edition -- the information is essentially the same but the 2011 is printed on cheap paper and the contrast between text and background for most of the illustrations is lousy, e.g. black text on a dark grey background, white text on a light grey background. I found it very difficult to read. The online version (O'Reilly Safari Books OnLine) is slightly better because it allows you to magnify the low contrast images which makes them slightly more legible. Thankfully, access to the online version is included with the ink-on-paper book free via a scratch-off, lottery ticket-type insert at the back of the book. If I had to do it again, I'd skip the paper book from Amazon and just purchase electronic access via O'Reilly. This version is more legible and you can print important pages that you might want hard copies of to highlight, mark-up, etc.
