Zeno would probably know better than me for a "sub" but I looked in my 1984 Zenith CRSP module guide and it shows NO sub for a 9-153. At that time Zenith is showing the 9-153, 9-153-02, 9-153-03 and 9-153-08, and at that time the ONLY sub listed was a 9-153-03 in place of a 9-153-02.

IIRC the CRT TV's only used a 9-153 WITHOUT any -##
at the end. There may still be a little tag on the old
board. You should be OK fixing the old one. For hoz
out the part # is 121-831 subs to 921-500. The
only thing I worry about is the amount of damage,
never seen that so maybe something else started it
like the FBT.

After replacing the diode,capacitor and resistor that feed 260V to the video module I am back in business! Thank you for the precious help! Unfortunately the picture tube is not very good. Picture is quite dark even with brightness control turned at maximum. Tomorrow I will try to rejuvenate it with the ultrasonic rejuvenator. I do hope not to reduce its life. There also is a problem with UHF channels. While VHF is received satisfactorily UHF channels are received with a big amount of snow. I think the UHF tuner has a problem. The pushbuttons also have a problem. Sometimes pushing a button makes another position indicator to light up. I have never seen a relatively new tv setlike this one with so many problems!!!

We need to find that guy from Chicago who posts so many Zenith youtubes. He seems to know a lot about them. I think his name is Robert.

Unfortunately, those early 25V inline Zenith CRT's didn't hold up nearly as well as the older delta gun chromacolor II CRT's. They are not nearly as bad as a '90's-era Zenith tube; but, they could be a lot better than they are.

The 13", 17", and 19" versions of that inline tube held up much better than the 23" and 25" tubes. I was seeing weak 23"/25" versions of that tube in the early '90's. OTOH, I've seen some of those tubes last 25-30 years and still be strong.

Rejuvenation sometimes helps and sometimes it doesn't. Just make sure to use a good rejuvenator, such as a later B&K or Sencore.

Unfortunately the tv doesn't work. Inspecting it before giving it power revealed a blown out electrolytic. I removed the horizontal module (9-153) and found several other components dead. I'd need to know the exact type of the chassis. Informations found on various sites gave controversial advices. On front side there is clearly marked "Zenith Chromacolor II" but it has not the usual Chromacolor vertical or Horizontal chassis. It has a large power transformer but this chassis resembles much more to the System 3 chassis.
I found several NOS replacements for the horizontal module (9-153) but it appears there are several types of the 9-153 module. I found a 9-153-03, a 9-153-11, 9-153-12 and 9-153-13. Which one is the correct one? Any advice from you Zenith experts would me more than appreciated. I would like to restore it at its best as it witnesses a time where things were made to last.

It reminds me of my 1982 Zenith System 3 but I use the 9-181 series modules.
