REDUCED!!
For Sale here are 2 Pairs (Quad Set) of very rare NOS, NIB Mullard GZ34 Rectifier tubes.
I bought them a few years ago from a gentleman in Sweden (he purchased them in the 1990s from a now defunct tube wholesaler in Norway) for a project which never eventuated, and it is now time to sell them as they have become surplus to my requirements.
Both of these sets of two have identical production codes;
Pair 1: f32 B2D2 = 2ndweek of April 1962
Pair 2: f32 B2D3 = 3rdweek of April 1962
One needs to appreciate how rare it is to get a matched pair or even a matched quad set with such close production codes.
For correct identification of Mullard tubes:
The f3 is the type. In this case a rectifier
The 2 means it’s the second design change or iteration of this type.
The "B" stands for the Blackburn factory.
The 2 is the second digit of the year....1962
The D stands for 4th month or April (because D is the 4th letter of the alphabet.
The 2 or 3 in this case is the week of the month.
Thank you for looking and have a nice day!!
