Default Re: Mullard Valve Tester Card Project

The card 227 mystery has been solved, I have found it in one of my Mullard Test Card Index 5th Edition to be used for the Cossor 215P valve

In the front of this book it states that the following numbers have not and will not be allocated to standard cards
95, 98, 120, 128, 141, 165, 171, 172, 173, 175, 176, 198, 204, 216, 220, 226, 229, 231, 239, 247, 254, 260, 266, 275, 276, 281, 287, 289, 303, 305, 322, 324, 326, 330, 441, 448, 459, 481, 482, 483, 500, 503, 537, 538, 539, 540, 544, 545, 551, 556, 559, 564, 585, 588

So if any of the missing or no issue cards aren't on this list they may be in this booklet...
