Yeah, although almost none did to the same extent. Early Silvertone TVs actually outdo Philco for engineering of circuits to utilize specific loktal tubes rather than merely swapping sockets to use the types that were nothing more than octals on loktal bases (e.g. 7C5=6V6). The earliest postwar GE and Crosley sets used at least one apiece. Sylvania was augmenting 5U4 with 7X6 in its early 1950s sets;
Motorola also continued to used loktals very occasionally on certain runs of certain chassis into the early 1950s.
