Since 2008, Dr. Burkhardt Schwäbe in Hannover, Germany, has been building tube amplifiers that are quite different from almost all competitors due to their transformerless technology. The small product range is extended now by a special version of the power amplifier OTL MK III. The power at 8 ohms is stated to be 30 watts per channel, at 16 ohms (e.g. for various LS 3/5A versions) 2x 55 watts of continuous power. The price for the anniversary power amplifier is €6500 in Germany.
The company has also become known for its tube-equipped headphone amplifiers and preamplifiers working on the same principle. The HLP MK II model is now also available with a newly developed MM/MC phono section at a German price of €3450.
Another focus of the company is the restoration and sale of refurbished tape devices as well as master tape copies and timeless hi-fi classics.
