    I have a pair of old stock kt77 labled mullard on boxes and tubes with Blackburn markings, but can't find any reference to mullard kt77.

    Mullard never listed a KT-77 in their radio valve manuals. GEC/Genelex/Osram/MOV made KT-77. Can you post a photo?

    Thank you Thom for responding. After a little research, I think what I have is a pair of Mullard Xf2 single halo, welded plates, El34 that were labeled (chalk) as KT77 for some reason. They do not have the same base shape or double halo structure that the GEC KT77 had.

    I will post a photo or two in the next few days.

    If it says "Xf2" on the lower side of the glass, then that answers your question.
