Questions about electric components

[Professor Jones]

Hey,

I'm planning the recapping of my CRT (KV-21C5B), and I've just finished listing all the parts that I will replace. Three questions came up while I was doing this :

- 2 caps have the same value (33 uf, 160v) but have different sizes. One is 2cm high and has a 1 cm diameter, and the other one is more bulky : 3 cm high and 2,5 cm diameter. What gives ?

- I noticed that one inductor had some kind of sticky stuff on top of it (https://photos.app.goo.gl/asGtWtjHvapdiSEx5). Should I bother changing it ?

- One cap is listed as ceramic in the service manual but in the TV it's a poly one that's installed, and it looks deformed. Would it be a good idea to replace it with a ceramic one ?

Thanks !

In the same order as above:

- Nothing to worry about. A 33uF 160V electrolytic cap is going to work the same way regardless. Height or footprint issues might mean one fits better in a given spot, but it might have also been whatever the OEM could get cheap.

- The fact i need you to tell me exactly which inductor in that photo is the problem probably indicates there ins't really a problem

- I'd advise going with what works. You know the polymer cap does. Try a ceramic by all means, but it might have been a misprint. Old service manuals often contain one or two errors.
