SKU: PF_12A-MKII Categories: ,


The 12A-MKII is a high current, high efficiency filter that is a perfect fit for an egress filter in an advanced power conditioner. It also serves very well as a standalone filter for high power loads, such as Vacuum Tube Amplifiers, high power Class A Amplifiers, etc. Due to its extremely low impedance at low frequencies and advanced filtering and ground loop braking techniques this filter provides clean power for the most dynamic sound reproduction.

The filtering methodology and schematics have been approved by hundreds of audiophiles who have been using filters by MyElectrons as from the year 2014. The Elite+ series builds upon the third, improved generation of Power Line Filters for Audio by MyElectrons and Thrive Audio. Mark II gets boost in the depth of RF noise suppression by its extra stage of filtration – it is a 9th order filter.

For the optimal EMI and Noise Suppression the load current of this variant of the filter should be less than 12A RMS. The filter can sustain up to 16A RMS of the load indefinitely.

Unrivaled level of EMI / noise suppression for high current power lines
The filter deploys common-mode transformers of the highest inductance value practically available on the market for the specified load current. This ensures high efficiency of the common-mode EMI suppression.
Two RF and two high inductance differential EMI filtering coils, combined with top grade metal film polypropylene capacitors, form a very efficient barrier for the differential EMI / noise.
Careful dampening of both common-mode and differential filtering circuits ensures resonance-free, quiet operation of the filter.

Ground Loop braking is more efficient and safer than found in most commercially available Hum Suppressor / Eliminator competitors products.
Use of a custom-built Ground Wire Choke provides for a system free of high frequency ground wire loops. Careful dampening of the choke prevents resonance effects. Current handling capacity of the grounding circuit is rated at more than 250A for 1s.

Zero Noise Surge Protection
Surge / overvoltage protection is applied between the load and neutral lines. Both lines are fused.
The Thrive Audio’ signature self-resetting, Zero Noise surge protection circuit is a novelty in power line filtration and protection technology. An overvoltage protection solution of a comparable quality can be found in high-end  professional measurement equipment.

High efficiency Power and Phase Indicator, an elegant and very power efficient solution that can be found in power line filters by Thrive Audio and MyElectrons. The indicator, and hence the whole filter, consumes less than 0.1W of active power.

Elite grade parts
Capacitors by WIMA, renowned by the audiophile society. Top quality inductors by Thrive Audio and Triad. Low impedance fuses by Littelfuse.

    I received the filter in a “tiffany box” where the board are fixed in a wood frame and all are fitted in a vacuum bag !!!
    I test this filter in strong 2000mV dirty electricity environment with a very effective reduction of EMI at about 20 mV.
    Before this, i have tested numbers of EMI filter with poor results or no reduction at all. I tested some important emi filter product and also ebay (chinese ?) product.
    Under lab test this filter are able to reduce EMI starting from 600Hz with a strong filter slope.
    Usually emi filter act from 500KHz or 1Mhz or more higher frequency and are not effective in audio range,
    For that reason i think this is the best filter to built one of the better power conditioner for hifi – hiend on the market ( i spent many times to study and understand commercial products).
    The ability of this filter to manage strong current request from power amplifier is out of the question.
    There are many reasons to suggest one single filter for single hifi devices, the audio quality improves a lot !
    Serge, the 775mv owner, is very kind person and help me to implement this filter in a better way.

    I degree in electronic and i live in Milan , Italy.

    Hello. My adventure with the Elite + 12 A MK2 filter began with searching the Internet for something effective in filtering electricity to my system. It is true that my system is equipped with a conditioner, but I thought that it would be worth adding something additional. I wrote to the owner regarding the filter and after exchanging a lot of e-mails, I decided to buy it. When I received the package with the filter and unpacked it, it made a great impression on me with its size and aesthetics. Of course, I will add that it has only advantages in terms of sound. I think that at the moment there is no other product on the market a better filter with such a well-thought-out topology. Even in very well-known conditioners, it will be difficult to find such refined filtration. It is really a very good filter. I can recommend it to anyone who wants to increase the value of their system. The owner himself is a very nice person, open and very helpful with a very extensive knowledge and education in electronics. Best regards, Serge. My name is Michał and I live in Poland
