In the vast world of electronics, some devices retain their relevance and charm despite the passage of time. One of these is the FP-200 / FP-250 power supply, manufactured by the renowned Yaesu-Musen back in 1968. This power unit has been a reliable companion for countless radio amateurs over the decades, providing stable and consistent energy for a wide range of radio transmitters.

Recently, I had the opportunity to work on one of these venerable devices. However, time and wear had taken their toll, leaving the original power transformer short-circuited. Determined to bring this piece of electronic history back to life, I embarked on a complete restoration project.

The first challenge was replacing the damaged transformer. Thanks to my in-depth knowledge of the unit and my expertise in electronics, I designed and built a custom replacement transformer, the 24S85 model. This transformer was engineered as an exact replica of the original, ensuring a perfect fit inside the chassis without the need for any modifications or drilling. Moreover, the 24S85 transformer features a standard 230-volt primary winding, ensuring full compatibility with modern electrical networks.

My restoration work went beyond simply replacing the transformer. I performed a complete series of inspections and additional repairs to ensure the unit was fully operational and safe to use. From re-soldering connections to replacing worn-out components, every detail received attention to guarantee optimal and long-lasting performance.

It’s worth noting that the 24S85 replacement transformer is not only a repair solution for the FP-200 / FP-250 power supplies, but also an opportunity for all owners of these units to preserve and maintain their beloved equipment. Thanks to its precise design and high-quality materials, the 24S85 transformer provides a reliable and durable power solution for vintage radio transmitters.

If you’re looking for a replacement transformer for your FP-200 / FP-250 power supply, don’t hesitate to contact me to order the 24S85 model. With my commitment to precision and quality, you can be sure to receive a product that meets your expectations and brings your cherished Yaesu-Musen device back to life.

In conclusion, this repair and restoration experience is not only a testament to the longevity and quality of Yaesu-Musen electronics, but also an example of the dedication and ingenuity that define the amateur radio community. Whether you’re restoring a vintage unit or preserving a piece of electronic history, the 24S85 transformer stands as an excellent choice to ensure continuous and reliable operation of your FP-200 / FP-250 power supply.

I’m excited to introduce my latest product, the LUX70-MZ output audio transformer, specifically designed as a replacement and upgrade for Luxman MQ70 amplifiers. With the original transformers long discontinued and increasingly rare, I developed an electrically compatible solution that maintains — and in many cases exceeds — the performance of the originals. The LUX70-MZ offers a high-quality alternative that can be installed easily with only minor adjustments to the amplifier.

Main Features:

The LUX70-MZ output audio transformer has been precisely engineered to perfectly fit Luxman MQ70 amplifiers and provides the following key features:

• Compatibility and Performance Upgrade: Our transformers have been thoroughly tested and shown to deliver improved performance compared to the originals. With our product, users can experience a clearer, more detailed, and engaging sound. You can see the measured results in this article.
• Easy Installation: With only four mounting holes, the LUX70-MZ transformer can be installed quickly and securely. It requires minimal modifications to the amplifier chassis and a small tweak to the feedback network, ensuring a smooth and trouble-free replacement process.
• Versatile Use: Besides being a compatible replacement for the Luxman MQ70, the LUX70-MZ can also be used in custom projects employing EL34 tubes in push-pull configuration. This versatility makes it an ideal choice for audio enthusiasts who wish to design or customize their own amplifiers.

The LUX70-MZ output transformer is an outstanding option for those who want to enhance the performance of their Luxman MQ70 amplifier, or for builders designing a custom EL34 push-pull amplifier. With its high-quality construction, ease of installation, and flexible application, the LUX70-MZ is the perfect choice for demanding audiophiles seeking the best from their equipment. Below is the frequency response graph measured at 6 watts on the actual amplifier:
