​Headphone amplifier
Röcklinger HPA1 OTL

 A unique product, probably the only pure OTL headphone amplifier on the market.

​RIAA amplifier
Röcklinger PHA2

Balanced RIAA amplifier with an outstanding signal to noise ratio. 

OUR PHILOSOPHY

Creating the perfect sound requires careful work, technical expertise and a strong will to succeed. Our goal is to deliver high quality audio equipment true to the original sound and ensure that our customers feel more than satisfied. At Röcklinger we attach great importance to the fact that every detail counts. 
Luckily enough it (PHA2) is not only an engineering product, it also sounds really, really good. I would like to state that it is comparable with other RIAA amplifiers 2-3 times the money." 
​​- Stefan Bystedt (Akkelis Audio)
Read the excellent review the Röcklinger HPA1 OTL headphone amplifier got from one of the biggest Hifi magazines in Sweden (in swedish). Read article.

Electronics fair in Göteborg
2017-03-09
The 8th and 9th of March it was time for the big electronics fair in our home town. Röcklinger was there to take part of the event. Many interesting things to see and new contacts were established. As you may know, we have new products and new designs under development and we are looking for reliable partners to work with. It seems like Hans enjoyed the fair and was very happy with the outcome, you decide.
Input impedance analysis
2017-02-15
This is how we at Röcklinger set up LTspice for input impedance analysis
Use a current source with the fixed magnitude of 1 Ampere:
  1. In parallel with the input.
  2. In a point in the circuit where analysis is required.
Burst of DC supply
2017-01-31
Here is another tip for you to tackle a possible problem with burst of the DC supply. As usual we at Röcklinger are happy to share our knowledge for those interested in detail construction.
Output transformerless links
2016-11-09
The first amplifier Röcklinger launched was a headphone amplifer, build with tubes with OTL technique. OTL stands for Output Transformer Less. To learn more what OTL is we share with you some usefull links for the curious. 
To measure input impedance
​2016-10-22
We at Röcklinger always simulate the electrical design first, then we build the circuit, measure and improve the design. This loop continues until we are confident that the final design is flawless. We also like to share and prove our design. So here is a tip on how to simulate input impedance using LTspice.
