    Amp archive is showing model # 784 -128
    But Merren only has # 784 -139.

    I'm confused is there difference?

    The typical OT is Drake 784-128, later ones a Drake 784-139. The choke a Drake 354-114 (3H, 100R, 250mA). PTs were lay down Drakes, you find 1202-118 on early ones (B+ around 430v) and some with 1202-133 PT which are more like 460-470v.
    Typically tube rectifier and steel chassis, occasional oddities as usual.
