Details:

It is just my opinion and I would rather paint a bleaker picture of something rather than saying it is better than it is.

Cd record still plays ok. Very good used light scratching to both the case and CD record. Like new used but no obvious signs of use.

If I say untested. By buying on this item you agree to these stipulations and to follow the instructions of the post office, or carrier.

Fair the CD record plays, sometimes skips. Cd record does not play. This means that I have tested something not to its full extent.

In photographs we occasionally use props to display items in the best light possible. In these cases it is best buying on it as if it was broken.

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

Light scratching to the case cover.

Cd still plays well.

If you're unhappy with an item. I am quite harsh on what is good and bad.

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. I try to resolve any issue to both our best interests. They will normally want to see the item and packing.

May be good or above. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case.

All tubes purchased have loads of life left in them. Please realize when buying antique, vintage or used equipment that they can not be in an absolute mint or absolute perfect condition, they might need some service, now or later.

Then they are not included in the sale. So to recap. 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.

Cover is in good condition but has normal wear and tear. Unless a collectors item, then low and weak tubes are unceremoniously thrown in the nearest trash can.

Slightly heavier than above.

Fully working. I have 4 of these machines and all display a slightly differing value if I test the same tube, as two testers are never the same. Heavy scratching to the disc.

Vacuum tube testing I do not sell just passable vacuum tubes. This offer is for a if it does not say base, stand, table, my wife, in either the main body of the or title.

Photos shown in this listing are of the actual item for sale.

Via messaging. This is a process, and it takes time.

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.

That is what they are there for. May be very light scratching but not noticeable or the case cover may be scuffed a little excellent very light ware to both the CD record or case cover. Most have one.

In regards to the case or cover, then the case cover is just holding itself together.

If not fully tested, then items are not tested to the full extent and may have something wrong that I have not discovered. I take lots of pictures so you can see cosmetics.

Use the zoom function and have a good look. When using the word matched it means in test results rather than in cosmetic looks. Then I have not test it.

So take a good look. Light and medium scratching. Medium to heavy scratching.

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.

If fully tested then that is what they are. The numbers letters in parentheses are equivalents put in to help people to find the correct tube.

Or have only gone so far to test it. I make mistakes once in a while. I do not publish test results in the listing as what I get, and what someone else might get can be different. I use a tv7 u military spec tester which is calibrated.

It is impossible to describe every scratch, scuff or mark.

So this shows what I get, and what you get may be slightly different.
