Details:

In photographs we occasionally use props to display items in the best light possible. So take a good look. This is a process, and it takes time.

When using the word matched it means in test results rather than in cosmetic looks. I can test the same tube on each tester and get differing results on each.

Most have one. If fully tested then that is what they are.

Fully working. Cd record does not play. Cd still plays well.

Very good plus used, some light scratching to either the case or CD record.

Fair the CD record plays, sometimes skips.

Very good used light scratching to both the case and CD record. All tubes purchased have loads of life left in them. Light and medium scratching 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 just my opinion and I would rather paint a bleaker picture of something rather than saying it is better than it is.

In regards to the case or cover, then the case cover is just holding itself together. By buying on this item you agree to these stipulations and to follow the instructions of the post office, or carrier. Cover is in good condition but has normal wear and tear.

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

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. Heavy scratching to the disc.

They will normally want to see the item and packing. Via messaging.

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

If I state any values they are for a guide only. If not fully tested, then items are not tested to the full extent and may have something wrong that I have not discovered.

Like new used but no obvious signs of use.

Vacuum tube testing I do not sell just passable vacuum tubes. So to recap.

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

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

Then they are not included in the sale. 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. 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. This means that I have tested something not to its full extent.

All tubes have passed the gas and short tests.

Rectifiers and diode tubes do not have trans conductance values. May be good or above.

Medium to heavy scratching. Use the zoom function and have a good look.

That is what they are there for. Or have only gone so far to test it.

I take lots of pictures so you can see cosmetics.

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

This offer is for a if it does not say base, stand, table, my wife, in either the main body of the or title.

I make mistakes once in a while.

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. If you're unhappy with an item.

If I say untested. Please have a look at the pictures for the cosmetic condition. I am quite harsh on what is good and bad.

Light scratching to the case cover.

Hickok 752, military TV 7s etc. I try to resolve any issue to both our best interests.

Slightly heavier than above. Cd record still plays ok.
