          Stay away from these amplifiers if you don’t want to risk serious accidents. It is an outlawed design! Buy yourself a current solid-state amplifier of adequate power for your speakers (no less than 300w.) and you will live happily and carefree, your speakers will be grateful.

            Post-holiday re-request for help with biasing instructions for the “original” Fourier Sans Pareil amps? 🙂 Thanks, BH

                Sorry couldn’t help. The risk of frying your ESL is high with them. sold my Atmasphere last year and couldn’t be happier with a pair of class D mono blocks.

                    I totally agree. For eight months now Mola Mola Kaluga has opened my eyes and ears, and the A1s have thanked me!
                    Size, weight, power consumption and price that is only a small fraction of that of the usual Class A and AB amplifiers of similar power.
                    Moreover: performance and sound quality are unquestionably superior.

                  No Fourier Sans Pareil OTL owners here with access to a manual and/or biasing instructions? Thanks! BH

                    Hello!

                    I am in the process of having my vintage Fourier Sans Pareil OTL’s reconditioned.

                    The tech is very experienced, an electrical engineer by trade, but needs a copy of the Fourier Sans Pareil OTL manual, including the specific instructions to bias the amps.

                    Can anyone here please help?

                    @atmasphere

                    Thanks!

                    BH
