The VT-30 01A Sylvania CHS (Cathode Ray Tube) model is a vintage computer terminal, known for its durability and reliability. Here are some pros and cons to consider before making a purchase:
Pros:1. Durability: CRT terminals, like the VT-30, are known for their robustness and longevity. They can withstand heavy use and are less susceptible to damage from dust and other environmental factors compared to modern flat-screen displays.
2. Functionality: The VT-30 is a versatile device that supports various communication protocols, such as ASCII, EBCDIC, and SNA. This makes it a good choice for users working with older mainframe systems.
3. Nostalgia: For some, the vintage look and feel of the VT-30 can be an appealing aspect. It may also be a collector's item for those interested in the history of computing.
Cons:1. Size and Weight: CRT terminals are significantly larger and heavier than modern flat-screen displays. This can make them difficult to transport and may require additional space for storage.
2. Power Consumption: CRT terminals consume more power than modern flat-screen displays. This can result in higher energy costs and may contribute to a larger carbon footprint.
3. Limited Resolution: The VT-30 has a relatively low resolution compared to modern displays. This may make text and graphics appear less crisp or detailed.
Conclusion:The VT-30 01A Sylvania CHS is a robust and versatile device with a vintage aesthetic.

Ultimately, the decision to purchase the VT-30 01A Sylvania CHS should be based on your specific needs and preferences.
These audio tirades are becoming harder to find. 01as are early ix based audio tirades commonly used as detector tubes in early turf radios. These both display the date code of c4.
Both tubes were tested on a calibrated Hickok TV 7. As pictures depict, these are not early engraved based tubes. Unfortunately one of the original boxes deteriorated and was discarded before I acquired these tubes.
No shorts or leakage was found both tubes were allowed to idle with filament current for 10 minutes prior to taking gm measurements. These are later production tubes ordered by the us navy. Both were tested for gm mutual conductance,shorts and leakage.
