4 National Matsushita 6CA7 EL34 Premium Tubes Matched Quad?

#matsushita
I received this as a gift from someone who said it was a matched quad set that they had used a few times a long time ago.
At that time, they had it checked and were told there were no problems.
After that, I might have used it once with a Lux push-pull amplifier, but basically, I didn't use it and kept it in storage for several years.
For this listing, I have only performed a visual inspection.
I have not checked it with any instruments.
I just looked at them and took pictures, but some of them had stickiness on the base. They might have had tape or something wrapped around them for identification before they came to me.
Other than that, I don't think there were any particular issues with the exterior.
I have not tested them on an actual device.
As they are old, there may be some age-related changes, including characteristics, compared to when I first obtained them.
I apologize, but my eyesight is poor, and I may misidentify the vacuum tubes.
I believe most of you who are looking here are knowledgeable and have excellent judgment, and can discern the details from the photos.
Please only purchase if you can judge from the photos and agree to the entire description.
If there is any discrepancy between the title/description and the photos, the photos take precedence.
I will ship via the available #Mercari-like shipping service.
If your purchase is on or around a weekend or holiday, shipping may be delayed until after the holiday.
As there will be transportation involved, and many identical items are available, problems may arise after arrival. Please understand that I cannot accept cancellations, claims, returns, or refunds.
Thank you.
