Nice new old stock, Mullard British made gold pin ECC801s tubes. These ECC801s are physically identical to CV4024 M8162 Mullard except that they have gold plated pins. These tubes have "double-flange" anodes (plates), Mullard "R" manufacturing code (Mitcham, Surrey, England) and 1970's era date codes. 

They are boxed and labeled as shown in the photo.
