If the transistors are still plugged in on the 9-57 solder
them in. The sockets are less reliable than the parts. Lots
of ints especially IC's. Later rebuilts had them removed.
Absolutely. I used to solder every transistor in every Zenith module, particularly the later vert chassis. Fortunately, the chassis mounted sockets were far better than those on the modules.
