These are ORIGINAL old wireless/radio valves - stock from my shop - Fagin's Phonograph Emporium - which was in Highbury, London from the late 1970's until the end of the 1980's.
The valves are untested by me but should work perfectly since they have been stored in good conditions since the shop closed. I have many more valves for sale here on eBay.
I will mail worldwide - just tell me what you want to buy and where you live and I will calculate the postage.
As with all the items that I sell on eBay, I will refund the purchase price in full if the valve proves to not be as I have described.
