Review RCA Nos Globe 90v Voltage Regulator Engraved Base Vacuum Tube Tested

The UX-874 RCA NOS Globe 90V Voltage Regulator Base Vacuum Tube is a classic piece of electronic hardware, harkening back to the days of tube radio and television technology. This vacuum tube is a 90V regulator, specifically the UX-874 type, which was widely used in various applications to stabilize voltage levels in vintage audio and video equipment.

The UX-874 Globe tube features a robust construction, with a glass enclosure that houses the vacuum inside. The tube's base is designed to fit into standard socket configurations commonly found in vintage audio and television equipment, making it easy to integrate into restoration projects or vintage systems.

The tube itself is a NOS (New Old Stock) item, meaning it is a reissued version of an original tube that was manufactured in the past. NOS tubes are highly sought after by collectors and enthusiasts due to their authenticity and high-quality construction. The UX-874 Globe tube is no exception, offering excellent performance and reliability, making it an excellent choice for any vintage equipment restoration project.

In terms of specifications, the UX-874 Globe tube operates at a voltage of 90V and can handle a maximum current of 320mA. It is a triode tube, which means it can operate in both amplifier and voltage regulator modes. The tube's filament voltage is 6.3V, and it requires a 4.0W filament power.

Overall, the UX-874 RCA NOS Globe 90V Voltage Regulator Base Vacuum Tube is a must-have for any vintage electronics enthusiast or collector. Its classic design, high-quality construction, and excellent performance make it an essential component in any vintage audio or television system restoration project.

1. Authenticity: NOS (New Old Stock) tubes are original, unopened, and often unused parts from the past. They are often sought after by collectors and audiophiles for their vintage charm and perceived superior sound quality.

2. Reliability: Vacuum tubes, when properly maintained, can provide a reliable and long-lasting performance. They have fewer moving parts than solid-state components, which can reduce the risk of failure.

3. Unique Sound Quality: Vacuum tubes have a unique sound quality that some people prefer over that of solid-state components. This sound quality can be described as warm, rich, and nostalgic.

4. Customization: Vacuum tubes can be easily swapped out in many audio systems, allowing for customization and experimentation with different sound signatures.

1. Limited Availability: NOS tubes can be hard to find, especially for less common models like the UX-874. This can make them more expensive than newer, mass-produced alternatives.

2. Maintenance: Vacuum tubes require more maintenance than solid-state components. They need to be properly aligned, biased, and heated to ensure optimal performance.

3. Power Consumption: Vacuum tubes consume more power than solid-state components, which can increase the overall energy consumption of an audio system.

4. Noise: Vacuum tubes can produce more noise than solid-state components, especially at lower volumes. This noise can be annoying or distracting to some listeners.

The UX-874 RCA NOS Globe 90V Voltage Regulator Base Vacuum Tube offers a unique sound quality, reliability, and customization options that can appeal to audiophiles and collectors. However, the limited availability, maintenance requirements, power consumption, and noise production can make it a less practical choice for some users. If you are looking for a vintage sound and are comfortable with the maintenance and cost, then this tube could be a great addition to your audio system. If you are looking for a more modern, reliable, and low-maintenance option, then you may want to consider a solid-state component instead.

Details:

This is a process, and it takes time.

Cd still plays well. This means that I have tested something not to its full extent.

If fully tested then that is what they are. I also sometimes use a Hickok 752 for testing if state any values they are guide only.

Like new - used but no obvious signs of use. Very good plus - used, some light scratching to either the case or CD record.

Medium to heavy scratching. We check and describe the as much of functionality can.

When using the word matched it means in test results rather than cosmetic looks. Use the zoom function and have a good look. Light scratching to the case cover.

In regards to the case or cover, then cover is just holding itself together. Please have a look at the pictures for cosmetic condition.

May be good or above. Working within normal parameters photos shown in this listing are of the actual item for sale.

Or if this is in grading regard to the case cover then there may be cracks torn has rips along its edges scuffed quite badly. Cd record does not play. If not fully tested, then items are to the full extent and may have something wrong that I discovered.

It is impossible to describe every scratch, scuff or mark. If it does not say matched then please do consider them to be such. I have 4 of these machines and all display a slightly differing value if test the same tube, as two testers are never.

Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they collectors items. Plays well.

I make mistakes once in a while. By buying on this item you agree to these stipulations and follow the instructions of post office, or carrier. This offer is for a. If it does not say base, stand, table in either the main body of or title.

In regards to the case cover then this grading means or sleeve is badly torn, scuffed, cracked and falling apart. Fully working. Cover is in good condition but has normal wear and tear.

Vacuum tube testing I do not sell just passable tubes. Via messaging. New - unopened brand new, sealed.

I do not publish test results in the listing as what get, and someone else might get can be different. I take lots of pictures so you can see cosmetics.

May be very light scratching but not noticeable or the case cover scuffed a little excellent ware to both CD record. Very good - used light scratching to both the case and CD record. If you're unhappy with an item.

I am not a huge retail outlet. All tubes have passed the gas and short tests.

Rectifiers and diode tubes do not have trans conductance values. Sorry for you having to read this but would be surprised how many people think the items come with my table or a part of anatomy that I have accidentally caught on camera.

Most have one. All tubes purchased have loads of life left in them. I try to resolve any issue both our best interests.

Or have only gone so far to test it. Cd record still plays OK. I use a tv7 u military spec tester which is calibrated. It is just my opinion and I would rather paint a bleaker picture of something than saying better.

In photographs we occasionally use props to display items the best light possible. If I say untested. So this shows what I get, and you get may be slightly different.

It is up to you make a judgment call and decide if worth the risk of buying. I may have the same tube but from differing years matched up in test results, which means they cosmetically or internally look a little different.

The numbers letters in parentheses are equivalents put to help people find correct tube. So to recap. Slightly heavier than above.

Light and medium scratching.

Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint perfect condition, might need some service, now later. Heavy scratching to the disc. Then they are not included in the sale. In these cases it is best buying on as if was broken.

Fair - the CD. Record plays, sometimes skips. Then I have not test it.

Whilst I endeavor to put tubes together from the same year and look same, this is not always case. I also pack well. That is what they are there for.

They will normally want to see the item and packing.
