Review WESTINGHOUSE Early Pittsburgh Receiving Tuner Ra Ga Detector Amplifier

The **Westinghouse 307190 1920 Pittsburgh Receiving Tuner RA Detector Amplifier** is a meticulously crafted, mid-century radio component that embodies the engineering ingenuity of its era while offering modern enthusiasts a rare opportunity to restore or integrate vintage radio functionality into contemporary setups. Designed as a standalone **1920 Pittsburgh Receiving Tuner**, this unit is a self-contained, high-performance radio front-end that combines a **Regenerative Amplifier (RA) circuit** with a **detector stage**, allowing for precise tuning and signal amplification of AM broadcasts. Built with a sturdy, die-cast aluminum chassis, the tuner features a classic **dial-style tuning knob** paired with a **sliding band switch** for manual frequency selection, offering a tactile and nostalgic tuning experience that contrasts with digital alternatives. The **RA detector amplifier** at its core employs a vacuum tube (typically a 12AT7 or similar dual-triode) to generate and amplify weak signals, while the built-in detector demodulates the incoming AM waves, producing an audible output suitable for connection to a speaker or external audio system. This tuner was originally designed for use in **Westinghouse s 1920 Pittsburgh radio series**, a line celebrated for its durability and clarity, and its inclusion of a **regenerative circuit** a technique that enhances sensitivity by feeding a portion of the output back into the input makes it particularly effective for capturing distant or weak signals. Whether used as a standalone vintage radio component, a modular addition to a restored set, or even as a unique audio project piece, the 307190 stands as a testament to early 20th-century radio technology, blending historical charm with functional utility. Its compact yet robust design, paired with the distinctive **Pittsburgh branding**, makes it a prized find for collectors and audiophiles alike, offering both educational value and practical performance for those seeking to revive or experiment with analog radio techniques.

The **Westinghouse 307190 1920 Pittsburgh Receiving Tuner RA Detector Amplifier** is a vintage radio receiver from the early 20th century, designed for shortwave and medium-wave listening. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Historical and Collectible Value**

The Westinghouse 1920 model is a rare and well-regarded piece of early radio technology, particularly from the Pittsburgh Receiving Tuner series. It holds significant value for collectors of vintage electronics, especially those interested in the golden age of radio (1920s 1940s). Restored examples can command high prices at auctions or among enthusiasts.

2. **Technical Innovation for Its Time**

The RA Detector Amplifier was an advanced design for its era, featuring a regenerative circuit (similar to early superheterodyne principles) and a high-quality vacuum tube (likely a 160A or similar). It was capable of receiving shortwave signals, which was cutting-edge in the 1920s when most radios were limited to AM broadcast bands.

3. **Craftsmanship and Aesthetics**

The 1920 model is known for its sturdy construction, with a wooden cabinet, brass tuning dials, and high-quality components. The design reflects the art deco influences of the time, making it visually appealing to hobbyists and historians. The attention to detail in its construction is a testament to early 20th-century engineering.

4. **Educational and Restorative Potential**

For electronics enthusiasts or hobbyists, this radio offers a hands-on opportunity to learn about vintage radio theory, tube circuits, and restoration techniques. Rebuilding or repairing one can be a rewarding project, providing insight into early radio technology.

5. **Functionality (When Working)**

When in good condition, the 1920 model can still function as a radio, though its performance will be limited by the technology of its time. It may require a separate power supply (e.g., a 6.3V transformer) and careful alignment of its tuned circuits. Some users report success in receiving local AM stations or shortwave signals with the right antenna.

6. **Community and Enthusiast Appeal**

There is a dedicated community of vintage radio collectors and restorers who actively trade, restore, and share knowledge about such devices. Owning one grants access to this niche but passionate group, which can be both supportive and educational.

---

### **Cons**

1. **Rarity and Condition**

Original 1920 models are extremely rare, and even restored examples can be difficult to find. Many surviving units are in poor condition due to age, oxidation of components, or lack of maintenance. The risk of purchasing a non-functional or heavily damaged unit is high unless you are buying from a trusted seller with verification.

2. **High Cost**

Due to its rarity and collectible status, the price for a fully restored or authentic example can be prohibitively expensive often ranging from several hundred to over a thousand dollars, depending on condition and provenance. This makes it an impractical purchase for casual listeners or those on a budget.

3. **Complexity of Operation and Maintenance**

The 1920 model requires a basic understanding of electronics to operate. It may need a separate power supply, and tuning the receiver (aligning the tuned circuits) can be challenging without the right tools or knowledge. Tubes may need frequent replacement, and the vacuum tube itself can fail over time, requiring sourcing of vintage or modern replacements (e.g., 160A or equivalent).

4. **Limited Performance Compared to Modern Radios**

The 1920 model is not a practical replacement for modern radios. Its sensitivity, selectivity, and audio quality are far inferior to contemporary devices. It is unlikely to receive weak signals or provide clear audio unless in ideal conditions with a strong local transmitter. Shortwave reception may also be inconsistent due to the simplicity of its design.

5. **Lack of Modern Features**

Unlike modern radios, the 1920 model lacks features such as digital tuning, multiple band coverage, or built-in power supplies. It is a single-band or limited-band receiver, requiring manual tuning and often an external antenna for optimal performance.

6. **Ethical and Practical Concerns**

Some collectors or enthusiasts may be hesitant to purchase a vintage radio if it was originally part of a set or if its acquisition involves ethical dilemmas (e.g., looting of historical artifacts). Additionally, the environmental impact of sourcing rare components or restoring the unit should be considered.

7. **Time-Consuming Restoration**

Restoring a 1920 model to working order can be a time-intensive project. It may require cleaning oxidized components, replacing failed tubes, rewiring, and aligning the tuned circuits. For someone without experience in electronics, this could be a daunting task.

---

### **Conclusion**

The Westinghouse 307190 1920 Pittsburgh Receiving Tuner RA Detector Amplifier is a fascinating piece of radio history with undeniable collectible and educational value. It appeals to those who appreciate vintage technology, enjoy hands-on restoration projects, or are interested in the evolution of radio design. However, its practical utility is limited, and the costs associated with acquiring and maintaining it can be significant.

For the average listener, a modern shortwave or vintage radio kit (such as a crystal set or a more accessible tube radio) would be a more practical and affordable alternative. The 1920 model is best suited for collectors, hobbyists, or those with a deep interest in early radio technology who are willing to invest the time and resources into its preservation.

---

### **Recommendation**

- **Buy if:** You are a collector of vintage electronics, have experience with electronics repair, or are interested in restoring historical devices. You are prepared to invest the time and money required to acquire, restore, and maintain the unit. You value the historical significance and craftsmanship of early radio technology over modern convenience.

- **Avoid if:** You are looking for a practical radio for everyday use, are on a tight budget, or lack the skills or patience to restore and maintain a vintage device. You prefer modern radios with advanced features and ease of use.

- **Modern shortwave radios** (e.g., Ten-Tec Argonaut, Icom IC-R8600) for reliable performance.

- **Vintage radio kits** (e.g., crystal sets, simple tube radios) for a more accessible introduction to early radio technology.

- **Digital archives or simulations** of vintage radios for those interested in their history without the physical or financial commitment.
