    The RCA model T4-8A is the improved version of T4-8. Mainly reflexing of AF via IF stage, and 6B7 replacing the 6F7.
    Most probably for both chassis versions there are at least the following cabinet versions:
    Low profile T4-9 and T4-9A, Thombstone T4-8 and T48A and Cathedral T4-8 and T4-8A.
