How can it work so perfectly???

The porthole-era Zeniths were overbuilt with too many components to go bad. By the mid/late 50s, though, they were really hitting their stride. The only issue I have with B/W Zenith sets from the 50s is that the original picture tubes always seem to be very weak. Just my luck? I have a hard time thinking of a tube-chassis Zenith that either worked when I found it or came back to life with almost no effort. I have a very similiar Space Command 400; I've never done a thing to it. I'm not even sure if I ever took the back off! It does have a pretty washed out picture from what I recall. I haven't powered it up in maybe 5 years.
