【Rare, Excellent Sound】Mullard ECC83 (12AX7) Original UK Made

Thank you for viewing.
This is an original ECC83 (12AX7) made by Mullard, a long-established British brand.

I purchased this as vintage NOS (New Old Stock) about 30 years ago at the Radio Center in Akihabara (Sakuraya Denki, if I recall correctly). I believe it cost around 10,000 yen at the store back then.

I only used it a few times for testing purposes at the time, and I estimate the total usage time to be less than 3 hours. Since then, it has been carefully stored as a one-owner collection item. I am now selling it due to equipment consolidation.

[Product Features]
Genuine Original Product: This is a vintage item manufactured in the UK at the time, not a reproduction.
Appearance: The getter (plated part) on the top and the shape of the tip (chip-off) are very beautiful, showcasing the skilled craftsmanship of that era.

Print: The manufacturer and model number print has some rubbing and peeling. Please handle with care as this is a characteristic of vintage Mullard prints, which are very delicate and prone to peeling.

Condition: Due to age, there is some slight darkening (oxidation) on the pins, but this is a natural condition for a vintage item.

Operation: Sound output has been confirmed for this listing. There is no crackling or noise, and the sound is excellent. You can enjoy the rich, lustrous tone characteristic of Mullard.

[Accessories]
It will be delivered in its original box for a MAZDA ECC83.

[Important Notes]
Please only purchase if you understand that this is a very old, precision electronic component and a vintage item. It will be shipped securely packed with cushioning materials.
