Review STROMBERG CARLSON Vintage Tube Amplifier And The Fisher Pre Amp

Stromberg-Carlson 50-PR AR-37 Tube Amplifier (Fisher Model)

The Stromberg-Carlson 50-PR AR-37 Tube Amplifier, also known as the Fisher Model, is a legendary piece of audio equipment that has graced many high-end audio systems since its introduction in the mid-20th century. This amplifier is a testament to the golden era of vacuum tube technology and its ability to deliver rich, warm, and detailed sound.

The 50-PR AR-37 is a dual-mono design, meaning each channel operates independently, ensuring superior stereo imaging and a more authentic sound stage. Each channel includes six output tubes - four EL34 power tubes and two 12AX7A preamp tubes. These tubes are known for their ability to produce a full and dynamic sound, with a balanced frequency response and a natural, unforced tonality.

The amplifier boasts a robust power output of 50 watts per channel into 8 ohms and 65 watts per channel into 4 ohms. Despite its power, it maintains an impressive level of control and finesse, making it an excellent choice for a wide range of speakers and listening preferences.

The 50-PR AR-37 is adorned with a sleek, silver faceplate, featuring large, easy-to-read meters for monitoring output power and voltage. The control layout is simple yet effective, with inputs for both phono and line-level sources, as well as a toggle switch for selecting between high and low sensitivity inputs.

The amplifier's transformer design is a key factor in its sonic performance. The large, custom-wound transformers provide ample current and headroom, ensuring that the output tubes are never pushed too hard, even during the most demanding passages. This results in a clean, distortion-free sound, with plenty of headroom for cranking up the volume when desired.

The 50-PR AR-37 Tube Amplifier is a true audiophile's dream. Its rich history, iconic design, and unparalleled sound quality make it a must-have for any serious music lover seeking an authentic and engaging listening experience.

The Stromberg-Carlson 50-PR AR-37 tube amplifier, also known as the Fisher AR-37, is a vintage audio component that has gained popularity among audiophiles for its unique sound and historical significance. This amplifier was first manufactured in the late 1940s and was widely used in radio and television broadcasting applications. Here are some pros and cons of buying this amplifier:

1. Unique Sound: The AR-37 is known for its warm, rich, and full-bodied sound that is not commonly found in modern amplifiers. This sound quality is a result of its design using vacuum tubes and transformers.

2. Historical Significance: Owning a vintage amplifier like the AR-37 is a badge of honor for audiophiles who appreciate the history of audio technology.

3. Build Quality: The AR-37 is built using high-quality components and has a solid construction that can last for decades with proper maintenance.

4. Flexibility: The AR-37 can be used to amplify a wide range of audio sources, including phonographs, radios, and tape players.

5. Collectible Value: The AR-37 is a sought-after collectible among vintage audio enthusiasts, and its value is likely to appreciate over time.

1. Power Consumption: The AR-37 consumes a significant amount of power, making it less energy-efficient than modern solid-state amplifiers.

2. Maintenance: Vacuum tubes and transformers require regular maintenance, including replacement of worn-out components and alignment adjustments.

3. Size and Weight: The AR-37 is a large and heavy amplifier, making it difficult to transport and requiring a sturdy stand or rack to support it.

4. Compatibility: The AR-37 may not be compatible with modern audio sources, requiring the use of a preamplifier or other conversion devices.

5. Cost: The AR-37 can be an expensive amplifier to purchase, especially if it is in good working condition and has been well-maintained.

The Stromberg-Carlson 50-PR AR-37 tube amplifier is a unique and collectible piece of audio technology that offers a rich and full-bodied sound quality. However, it comes with some drawbacks, including high power consumption, maintenance requirements, and compatibility issues with modern audio sources. If you are an audiophile who appreciates vintage audio technology and is willing to invest in the maintenance and compatibility requirements, then the AR-37 may be a worthwhile investment. However, if you are looking for a modern and energy-efficient amplifier that can easily amplify modern audio sources, then you may want to consider other options.

If you are interested in the Stromberg-Carlson 50-PR AR-37 tube amplifier, I recommend conducting thorough research on its condition, maintenance requirements, and compatibility with your audio sources before making a purchase. You may also want to consider purchasing a refurbished or restored AR-37 from a reputable dealer to ensure that it is in good working condition. Alternatively, you may want to consider modern solid-state amplifiers that offer similar sound quality and are more energy-efficient and easier to maintain. Ultimately, the decision to buy the AR-37 should be based on your personal preferences, budget, and audio requirements.
