(Sorry about the blurry image) This is a NOS "True Mullard" 5AR4 rectifier. It has a date code of B014, indicating 1970 production at the Blackburn, England plant. Here is a picture of the date code:

The box is in lousy shape, the printing has been rubbed a bit from the box, but the tube is absolutely NOS and has never been used (except to test it). This is the later 7-serration plate version. If this had been branded with another name, it would have been a few dollars cheaper, but as a "True Mullard", it simply has to cost a little more. These things are getting REALLY pricey now. My stock is getting lower and the price simply has to rise.
As with all tubes I sell, I stand behind this tube with a 90 day guarantee (unless you obviously abuse it). Simply e-mail me at:
nostubesforyourdynack@gmail.com, and I'll take care of the rest. Don't pay $250.00 or MORE for a tube in similar condition from a major tube seller. Save money and get a guarantee to boot. I hope I can be of service to you.
Sincerely,
Bill Thomas
