These are UK made Mullard’s. They have the classic box-shaped plate.
I purchased these from Upscale Audio who rated these under their Platinum grading scale. Each tube has also been cryogenically treated by Upscale Audio’s cryo supplier. Each tube is in it’s original wrapping, pin protector, and box.
I have the original receipt from their purchase, showing $73 ea.
$104, sold only in pairs. One pair left, Buyer pays shipping cost.
These were going to be a backup set, however I switched to a different tube. If you like great midrange these are your tubes.... My loss your gain
