Elektor products are not kits like the others. Elektor circuits are sometimes quite complex. They are designed so that their assembly presents as few problems as might reasonably be expected. If the kits developed by Elektor are not particularly difficult to build, it is precisely because they are designed from A to Z to be replicated at home by many readers with equally varying levels and skills in electronics.

Eurocircuits Elektor Dual DC LISN (150 kHz - 200 MHz)
Measuring conducted emission is the simplest and most affordable method of getting some indication of whether a design can meet EMI/EMC requirements. A Line Impedance Stabilization Network (LISN) is an indispensable part of an EMC pre-compliance test setup. In cooperation with Würth Elektronik, Elektor has developed a 5 µH, 50 Ω Dual DC LISN that supports voltages up to 60 V and currents up to 10 A. The instrument measures RF interferences on both channels (the power supply) by means of 5-μH blocking inductances. The internal 10-dB attenuation network – one in each channel – contains a 3rd-order high-pass filter with a cutoff frequency of 9 kHz to protect the input of instruments like a spectrum analyzer from potentially harmful DC voltages or low frequencies coming from the EUT (Equipment Under Test). Specifications RF path Channels 2 (with clamping diodes) Bandwidth 150 kHz – 200 MHz Inductance 5 μH || 50 Ω Internal attenuation 10 dB Connectors SMA DC path Max. current < 10 ADC Max. voltage < 60 VDC DC resistance < 2 x 70 mΩ PCB size 94.2 x 57.4 mm Connectors 4-mm banana Hammond enclosure Type 1590N Dimensions 121 x 66 x 40 mm Included 1x 4-layer PCB with all SMT parts fitted 1x pre-drilled enclosure with ready-printed front panel layout 5x gold-plated, insulated, 4-mm banana sockets, rated for 24 A, 1 kV 1x Hammond enclosure 1590N1, Aluminum (Die-Cast Alloy) More Info Project on Elektor Labs: Dual DC LISN for EMC pre-compliance testing Elektor 9-10/2021: EMC Pre-Compliance Test for Your DC-Powered Project (Part 1) Elektor 11-12/2021: EMC Pre-Compliance Test for Your DC-Powered Project (Part 2)

Eurocircuits Elektor Fortissimo-100 Power Amplifier Kit
Celebrated Elektor audio design specialist Ton Giesberts has once again released a phenomenal design for a high-end audio power amplifier, the Elektor Fortissimo-100. Once again, the results of the amplifier on the test bench challenged Elektor’s high-spec Audio Precision test gear close to its noise floor. The specifications, ease of construction, and the overall stability of the Fortissimo-100 are deemed so good that Elektor are offering the project as a kit of parts for assembly at home, using plain tools. The kit contains each and every part to build one Fortissimo-100 mono block, including a set of high-quality PCBs, the heatsink, and other mechanical parts like standoffs and ceramic isolation washers for the power transistors. Again, all parts are through-hole. A detailed, step-by-step assembly guide (downloadable PDF) should enable every audio lover with the ability to work accurately and sensibly, to assemble the mono block and ravish at the sound quality. Two mono blocks are required to build a Fortissimo-100 stereo amplifier, plus a symmetrical 40-V, stabilized power supply per amplifier. Don’t use a single power supply for two amplifiers! The supply is not included in the kit, but a suggested source is given in the description for the project, so readers can opt for their personal desires.

Readers and interested parties can submit their product ideas and, together with the Elektor development team, a finished product can be brought to market after extensive consideration and many tests. Note that these are always small series production runs, so the products are considered 'Elektor Collector Items'.
