Details:

It is impossible to describe every scratch, scuff or mark. Light scratching to the case cover.

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. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case. Please have a look at the pictures for the cosmetic condition.

This is a process, and it takes time. I try to resolve any issue to both our best interests.

Very good plus used, some light scratching to either the case or CD record. During ww2, military need for vacuum tubes created a large shortage of tubes that could be purchased by civilians. I take lots of pictures so you can see cosmetics.

It is just my opinion and I would rather paint a bleaker picture of something rather than saying it is better than it is. So nos refers to the test results rather than it is brand new and never been out of it's box.

When using the word matched it means in test results rather than in cosmetic looks. Fair the CD record plays, sometimes skips.

Medium to heavy scratching. Or have only gone so far to test it. By buying on this item you agree to these stipulations and to follow the instructions of the post office, or carrier.

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. If fully tested then that is what they are. Distinguishes from a metal envelope tube.

If I say untested. Use the zoom function and have a good look. If a tube has been used, even for only one second, then it is used.

Backwards compatible with earlier designs.

Cover is in good condition but has normal wear and tear. So take a good look.

I am quite harsh on what is good and bad. 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.

If I state any values they are for a guide only. 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.

If you're unhappy with an item. In regards to the case or cover, then the case cover is just holding itself together. Cd record still plays OK.

Via messaging. Backwards compatible with earlier designs.

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.

In photographs we occasionally use props to display items in the best light possible. Cd record does not play. Or if this is in grading is in regard to the case cover then there may be cracks in the case or the cover is torn, or has rips along its edges or scuffed quite badly.

It is up to you to make a judgment call and decide if it is worth the risk of buying. 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. 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.

All tubes have passed the gas and short tests. That is what they are there for.

If not fully tested, then items are not tested to the full extent and may have something wrong that I have not discovered. The a improvements were primarily controlled heater warm up time and or low noise low hum.

Hickok 752, military TV 7s etc. Very good used light scratching to both the case and CD record. Slightly heavier than above.

Most have one.

In regards to the case cover then this grading means the case or sleeve is badly torn, scuffed, cracked and is falling apart. Then I have not test it.

5v tested photos shown in this listing are of the actual item for sale. I can test the same tube on each tester and get differing results on each. Rectifiers and diode tubes do not have trans conductance values.

This means that I have tested something not to its full extent. So to recap. Heavy scratching to the disc.

M r has absolutely no special audiophile connotation as soon as a tube is put into a tester, then, it is used. Light and medium scratching.

The numbers letters in parentheses are equivalents put in to help people to find the correct tube. 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.

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

May be good or above.

Then they are not included in the sale. I make mistakes once in a while.

In these cases it is best buying on it as if it was broken. Example 2a3, 6a3.

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.

This offer is for a if it does not say base, stand, table, my wife, in either the main body of the or title. To be frank there is no such thing as a new tube unless it has never been in a tester. Fully working.

Backwards compatible with earlier designs. Cd still plays well.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.

G glass envelope and octal base. Like new used but no obvious signs of use. All tubes purchased have loads of life left in them.

They will normally want to see the item and packing.
