Merry Christmas and Happy New Year

2017 has been a good year in terms of new developments. I have a new line of amplifiers, that is intended for a well known brand name.
I hope this evolves in to a long term cooperation.

I have also written a lot of new material for this portal. This will be published in the new year 2018.

I want to thank the hundreds of good people writing to me regarding my amplifier compendium. I have read every single of them, but I am afraid that it hasn’t been possible to respond to all. I encourage you to write to me, in particular if you have any comments about the compendium. I will do my best to reply to you, although that doesn’t always happen. But rest assured that I will read it and I appreciate any comments.

Globally 2017 hasn’t been the best year in the history og mankind.
New winds blows and it doesn’t look too good.

It is my hope that 2018 will be a year of progress and peace. Good people are working on this every single day.

With this in mind, I wish you all a merry Christmas and a very happy new year.

– sincerely

Happy New Year

Thank you all for the year that went. The insane killings of journalists in French by fanatic lunatics was a bad and sad start on a new year. It remains a mystery to me that these crazie persons choose to kill civilians, reporters and medical/red cross/moon helpers. There is no honor or glamour in such acts, just shame.

Now, this year I will upload tons of information, schematics and more at this homepage and I will gradually build up a stock of transformers for the users of tube/valve audio gear. Manufactures of high end audio, guitar amplifiers and the DIY community will hopefully find these online catalogs helpful.

I will announce here, when I once again take new orders in small quantity.

Currently no new orders.

As of 4 of January 2014 we regret that we do not take new orders from privates. Our order book is full for the next 7-8 months.

We are also in the process of developing some new advanced alloys for even better transformers to come.

Please, stay tuned.

So far so good.

It seems as if our email system is working again.

We will try to reconstruct as much of the former content as possible, but a lot got lost.

We apologize for this situation. Please, forward any question you may have and order via sales at

Lead time for the time being are 1-3 weeks. Products in stock will be shipped within 24 hours as of registered payment.

We will be closed from Friday the 12’th to Friday 26’th of July for vacation.

We wish you all a happy summer.

– sincerely Kurt Lilienthal

Real men use no back-up…….

As of now we have reconstructed some text based on biological memory, but mainly all are new.

Vacation and holidays will claim some of July and other more urgent tasks will steal our time this summer.

The main thing the rest of the year is to set up the new “in house production” of transformers and to maintain the high quality we were used to by our former suppliers of transformers.

If you spot any major language errors – well, or even small ones in the new texts, please do not hesitate to let us know.


Happy summer out there. This also goes for the hip hackers and rock ‘n rollers.

Maxwell, Faraday, Oersted and Henry will revenge the rip.
