1970s Zenith Console - Troubleshooting

[zeno]

Yup thats the original jug. Almost 50 yrs & still quite usable.
Make a list for subs. CC2 sets are real common & probably use
the same one. Just be sure its a 30 Kv tube. Hybrids will
have 25 Kv so no go. I think you have a 25VDQP22
check the Sams.
The set up looks good. Last test is turn off the lights & turn everything down low. If the pix gets sharper its CRT
