Special Note:

At present, the new FM300A complete machine with a new gold version of all-aluminum chassis has been newly built, and the price is 3380 yuan

The price of the original direct-engraved version of FM300A remains unchanged, still 2880 yuan

FM 300A is a classic power amplifier made by Swiss FM ACOUSTICS more than 30 years ago. The price of the original machine is 40 or 50, which is really expensive! With the most classic sound characteristics of FM, everyone knows that FM amplifiers are expensive, but almost everyone who has used them is convinced by their sound performance. More music details, richer sound levels, and more pure music tastes. The ultimate pursuit of enthusiast players. The price of this re-engraved FM300A is only 3980 yuan! It is guaranteed to have almost the same sound characteristics as the original machine, and it can be returned if you are not satisfied.

      FM300A is the only rear stage of RCA input in the FM power amplifier. It was the product of FM in the early days of the world. After it became famous, it was changed to F10B and changed to balanced input , The sound of this machine is more pure, the music is more appealing, and the sense of lines is clearer. With a pair of 17419 amplifier tubes, the driving force and control are good. The evaluation said that the sound is more beautiful than Daxiao 108 and tube amplifiers, the sound spikes the ordinary Daxiao models, the F10B push West Lake tower 12 and the Dynaudio C5 floor box are perfect.

        production process:

       This re-engraving is 100% completed according to the original machine, with exactly the same overall structure, exactly the same circuit routing, and exactly the same protection circuit, as much as possible Ensure that the same components are selected（This variety of transistors all use second-hand disassembled components carefully selected and matched） , Has sought infinite closeness to the original sound.

       FM is the Mount Everest in the audio. Since the beginning of the year, the old man and I have been working on this machine with a kind of reverence. The old man is more than sixty Years old, decades of unremitting exploration of audio circuits, has very rich experience, and has the rigor that young people cannot understand now. Listening to music every day, dealing with some repaired products or testing new circuits, I have fun and never tire of it. It is hard to imagine that in the few months from the beginning of the year to the present, the old man of this circuit has repeatedly tested and changed many times, and replaced and compared each component with a different brand until the final shape. The final test index is completely consistent with the original machine standard, 75W8 Euro is accurate. Looking at this simple and unsophisticated machine, it is really embarrassing to be able to restore the original sound of the sound so accurately. All the so-called fever freaks disappeared in an instant in front of this machine. Yes, we now have the conditions to make the routing more beautiful, but we can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t lose the true meaning of fever due to subjective beauty.What needs to be sighed is that too few people really carefully dig out the original state and sound characteristics of the circuit.The abnormal thinking that the stacking of fever components is good sound has led many people astray. This is what we need to truly reflect on!

        The appearance and circuit are exactly the same as the original machine, the same function settings, and the same protection circuit. During the circuit test, we felt a little bit of the subtlety of its design! The black box is not a mysterious thing, but even if the exact same components are given to ordinary DIY players, it will not be able to complete the production of this amplifier. Therefore, this circuit only provides the complete machine, and cannot provide kit sales!

1, Is re-engraving just stealing a copycat? Can you understand it this way?

Answer: There are different understandings and answers from different angles! First of all, these foreign machines have their own security measures（Like black box）, The price is high originally, if it is easy to be cracked and imitated, it has already been imitated. And we can see many imitation versions. It is difficult to say how much the original circuit can be understood and the sound can be. We take the mentality of learning and research to understand the actual level of this product produced by these old-brand capitalist countries after years of industrial development and the integration of local culture. In the process of imitation, I often stay awake at night. I am often moved by their meticulous design. I often sigh for the excellent products of that era. I am often impressed by the rigorous attitude of the designers at that time. We are a post-industrial developed country, and our own accumulation only has a few decades. At that time, we could only produce some simple products that satisfy production and life. If we talk about combining industrial products with our national culture and raising them to a certain height and displaying them on the world stage, we have to learn too much. It can be seen from the schematic diagrams published by various forums that this circuit is relatively simple, but it is not a very simple thing to really understand this circuit completely. It is not difficult to simply imitate a shape at the current level of domestic production capacity, but our goal is to thoroughly understand and grasp. In fact, it is also used as a standard to evaluate the specific level of our previous products.

2. Which speakers are suitable for pushing

      This power amplifier is not a high-power power amplifier, the normal output power is 8 ohms 80W/4 ohms 150W, suitable for most bookshelf boxes and floor boxes, the best sensitivity is above 86DB. In fact, the thrust and low frequency control of the FM300A power amplifier is better, and many difficult speakers can also be served.

 3. Do you need pre-stage

         FM''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s power amplifier itself has relatively large gains, and it can be directly connected to mobile phones/computers without the use of the front stage, not to mention CD and DAC problem. Of course, if you have a better front level, it will be better to connect it

4. What sound style of FM300A

       FM300A amplifierThe tone is more pure, the music is more appealing, and the lines are clearer. This is the evaluation of it on the Internet. Through our own test and comparison, I feel that this power amplifier has rich sound details, wide sound field, precise positioning and clear layers.

5. Is there room for polishing and improvement?

         At present, we have used good or suitable materials that we can get to do it, many of which are after repeated comparisons and made this power amplifier In the process, we also really felt that a good sound can be made without stacking with fever components.
