Parts is Parts!
On the block is this pair of Mullard 12AT7 dual-triode tubes.
One is marked with Tk1 over B8C, the other is marked with only RC9. If my research is correct, the one is from the Blackburn plant, made in the late sixties the other from the Mitcham plant date of manufacture unknown, most likely the same era.
They
have short (15mm) wing plates, top single copper post “D” getters. Printing is in good shape on one, the other not so good.
Tested on a
TV-7B/U military tube tester with one tube reading 72 on one section,76 on the other. Tube two section one reads 76 the other section 83 with 50 being good.
Sold as is for no
reserve.
