Light scratching to the case cover. During ww2, military need for vacuum tubes created a large shortage of tubes that could be purchased by civilians. Backwards compatible with earlier designs.
It is impossible to describe every scratch, scuff or mark. This means that I have tested something not to its full extent. So take a good look.
Like new used but no obvious signs of use. In regards to the case or cover, then the case cover is just holding itself together.
The photos are of one pair.
By buying on this item you agree to these stipulations and to follow the instructions of the post office, or carrier. If you know that both metal and glass versions were manufactured, then no suffix is a metal envelope tube example original 6l6, 6f6, 6v6, 6n6, etc were all metal envelope tubes. In these cases it is best buying on it as if it was broken.
May be very light scratching but not noticeable or the case cover may be scuffed a little excellent very light ware to the CD record or case cover.
Hickok 752, military TV 7s etc. May be good or above.
When using the word matched it means in test results rather than in cosmetic looks. Very good plus used, some light scratching to either the case or CD record. In regards to the case cover then this grading means the case or sleeve is badly torn, scuffed, cracked and is falling apart.
I can test the same tube on each tester and Get differing results on each. Very good used light scratching to both the case and CD record.
Slightly heavier than above.
This offer is for a if it does not say base, stand, table, my wife, in either the main body of the or title. If a tube has been used, even for only one second, then it is used. Fair the CD record plays, sometimes skips.
They will normally want to see the item and packing.
Distinguishes from a metal envelope tube. Photos shown in this listing are of the actual item for sale. So to recap.
Backwards compatible with earlier designs. I try to resolve any issue to both our best interests. Then they are not included in the sale.
In photographs we occasionally use props to display items in the best light possible.
I have more than one new pair for sale. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case. It is up to you to make a judgment call and decide if it is worth the risk of buying.
Cd record still plays OK. If fully tested then that is what they are.
I may have the same tube but from differing years matched up in test results, which means they may cosmetically or internally look a little different.
Use the zoom function and have a good look. M r has absolutely no special audiophile connotation.
If I say untested. It is just my opinion and I would rather paint a bleaker picture of something rather than saying it is better than it is sorry for you having to read this but you would be surprised how many people think the items come with my table, the wife's legs etc.
Heavy scratching to the disc. All tubes have passed the gas and short tests.
Light and medium scratching. If only one type of envelope was manufactured for that type, then no suffix simply refers to the tube being the original design of the tube. Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint or absolute perfect condition, they might need some service, now or later. So nos refers to the test results rather than it is brand new and never been out of it's box.
Suffixes that are useful when looking at tubes glass envelope, which distinguishes from a metal envelope tube ruggedest construction, meets mil 1 a us military specifications, and therefore most w tubes are us military inventory. GB 5 glass unflappable t9 glass envelope with local base gm or mg metal coated glass envelope with octal Basel mt 8 metal envelope and octal ox basely t9 glass envelope and octal ox base metal envelope and octal Basel t9 metal envelope with local base r while not technically a suffix, Mr when stamped on tube base only means that the tube was manufactured during ww2 for maintenance and repair of civilian radios. Example 2a3, 6a3.
If not fully tested, then items are not tested to the full extent and may have something wrong that I have not discovered. Spray shield coating on a glass envelope Tibet short glass envelope ruggedest construction, meets mil 1 a us military specifications McNeil base example 5y3wgta conveys a ruggedest us military issue tube with a small glass envelope and newer design than original 5y3g.
I make mistakes once in a while. Cd record does not play. If I state any values they are for a guide only.
Medium to heavy scratching.
Or have only gone so far to test it.
A more complete list of suffixes and their exact meaning none without more context, a tube with no suffix does not tell you very much.
I take lots of pictures so you can see cosmetics. Cd still plays well. If you're unhappy with an item.
Most have one. Rectifiers and diode tubes do not have trans conductance values.
Backwards compatible with earlier designs. Via messaging. To be frank there is no such thing as a new tube unless it has never been in a tester.
This is a process, and it takes time. Please have a look at the pictures for the cosmetic condition. Vacuum tube testing I do not sell just passable vacuum tubes. I am human.
The numbers letters in parentheses are equivalents put in to help people to find the correct tube. As soon as a tube is put into a tester, then, it is used.
That is what they are there for.
Cover is in good condition but has normal wear and tear. I am quite harsh on what is good and bad. Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they are collectors items.
Then I have not test it.
All tubes purchased have loads of life left in them. The a improvements were primarily controlled heater warm up time and or low noise low hum.
