FOR SALE: I'm selling THREE Mullard ECC83/12AX7 Tubes. They are yellow print, grey ladder anodes with round halo getters. Made in Great Britain at the Mullard Blackburn factory. TWO are NOS matching pairs with Blackburn codes I61 B4C4 - as new logo. ONE is a spare with Blackburn code B4C4 - slight wear to logo. All test strong & balanced. Sound superb! I originally bought them to use in a project which didn't get off the ground. Looking for £100 for the matched pair and £40.00 for the spare.
