Review MFJ Original Filter Clean Very Nice Audio 3-way

The MFJ-751 Audio 3-way Filter Clean is a comprehensive solution designed to improve the performance of your audio equipment. This high-quality filter cleaner is specifically engineered to remove dust, debris, and oxidation from your audio components, ensuring optimal sound quality and extended lifespan.

The MFJ-751 is a 3-way filter cleaner, meaning it can be used on a wide range of audio equipment, including amplifiers, speakers, and receivers. It uses a non-conductive, non-flammable liquid that safely and effectively removes build-up without causing damage to the delicate components inside your equipment.

The filter cleaner comes with three separate nozzles, each designed for different types of filters. The first nozzle is a narrow, pointed tip for reaching tight spaces and small filters. The second nozzle is a wider, flat tip for larger filters and surfaces. The third nozzle is a straw-like applicator for reaching deep into vents and hard-to-reach areas.

To use the MFJ-751, simply apply a few drops of the cleaning liquid to the nozzle of your choice, insert it into the filter, and gently push and pull the nozzle to dislodge any build-up. The liquid will dissolve the dirt and grime, allowing it to be easily wiped away. The filter cleaner is odorless and leaves no residue, so there's no need to wait for it to dry before using your equipment again.

In addition to its cleaning capabilities, the MFJ-751 also includes a built-in moisture indicator. This feature ensures that you're only using fresh, clean liquid, and alerts you when it's time to replace the bottle.

The MFJ-751 Audio 3-way Filter Clean is a must-have tool for any audio enthusiast. It's easy to use, safe for all types of audio equipment, and can help extend the life of your equipment while improving its sound quality. With the MFJ-751, you can enjoy clear, uninterrupted audio for years to come.

Condition used, working. It was the preferred filter type used by many long term short wave listeners hams on receivers like the Sp 6 HQ 129x, ken wood r600's, drake swl4 or r4a or r4b and many others. It is an good companion to any vintage tube radio which has only volume controls and or selectivity switches.

The controls and function switch have been cleaned with exit 5. The last picture is the picture I sent Mfj asking how to adjust them and shows the two trimming inter stage resistors. I opened a ticket with Mfj and Mfj service told me that the adjustment of the two resistor trimmer son the main board is simple using an insulated adjusting tool, peak for best sound.

This one was used on a Hammond HQ 129x and helped the operator log many foreign countries. Requirements simply patch the audio output of your receiver to the input rca jack on the rear apron and then plug your speaker into the sister rca jack or your headphones into the front phono connector on the front panel.
