Vacuum Tube Rectifier Tube Shuguang 5Z3P Shuguang Original Box New? Unused?

This item was given to me as a new product in the past.

I have only visually inspected it for this listing.

I used to call 曙光 (Shōkō) Shūguan in the past, lol.

Regarding the exterior, I only looked at it and took pictures, but as far as I could see, it looked clean, and I thought it might be new... It seemed to have no particular issues.

If you ask me to prove it's new, I don't know what to do, lol.

I have not measured it with any instruments before listing.

I believe it was manufactured about 10 years ago (or more?), so please only purchase if you understand this.

I have not tested it by loading it into a device.

My eyesight is poor due to presbyopia, so there may be misinterpretations or typos.

I apologize, but I ask that everyone with excellent intelligence and discerning eyes make their own judgment by looking more closely at the photos than I could.

Also, please only purchase if you understand what an untested item means.

Please only purchase if you can judge from the photos, and if you agree to the entire profile and description.

If there is any discrepancy between the title/description and the photos, the photos take precedence.

I will ship using the cheapest #Mercari_related_shipping method available.

If your purchase is on or around a weekend or holiday, shipping may be delayed until after the holiday.

There are many similar items circulating due to transportation, and problems may arise after arrival. I apologize, but I cannot accept returns or refunds for any reason, so please understand.

Thank you.
