Still working on my Sylvania

[jeyurkon]

That's an orange drop that someone used as a replacement and it should be fine. I can't tell from the photo but it looks like someone paralleled it with a bumblebee. The bumblebee should be replaced.

I'm guessing that this is C209 based on the location and it should be 0.2uF. I can't tell from the photo whether it's .015uF or 0.15uF. 0.15uF would work. .015uF wouldn't work very well. It appears to be part of the +300V boost.
If it's in parallel and it's .015uF they may have been trying to compensate for the bumblebee dying, in which case you'll have to replace both.

I'm not sure that I stated this very clearly.

The cap to the right of the 1,000V mica is a micamold mica. These are the buggers to distrust. I can't tell what brand the 1,000v one is.

Hi John,
That orange drop is a sprague .015/1600.
What do you mean by replacing both?
Should I just leave the orange in place and replace all the rest?

Is the orangedrop in parallel with the bumblebee? Is it C209 in the Sylvania schematic? The answer to your question depends on that.

The .015/1600 is soldered the the exact same spots as the plastic bumble bee in the background it is a .2/600 cap.

My guess is that the bumble bee started to go bad and they tacked the orange drop on to compensate. I'd replace them both with a single 0.2/600V film cap.

The coral colored one above them is a replacement also. I'm not familiar with that type, it's probably o.k. to leave alone. Perhaps someone else could chime in an opinion.

Yes back at the Sylvania.
The coral colored .01 cap is not pictured in the schematics.
But I replaced it with a new one..the yellow film caps.
I ran out of the yellow film .0047/630's..back ordered from Radio daze and ordered some from the Tube Store.
They sent me these orange ones .0047/600.
Never used these type are they okay for the tv?
I also finally got my order from Just Radios and had been waiting over a week for the 470pf/15KV's for the HV section. Well they forgot to put them in the baggie..bumber.
Radio Daze also had no more of the .0047/630's.

The orange caps are just fine.

The 0.01 cap, is that the 0.015/1600 cap you mentioned earlier? If so, did you remove it and the bumblebee and replace them with a single 0.2uF/630 cap?

justradios has made a couple of mistake with me too. But, they corrected them immediately.

No the .01 cap is the red one at the top of the picture(few messages up)
That brite colored red one is marked .01/600 it is not on the schematic that I can find.

I cut out the orange drop..maybe it looks more coral..it was 0.015/1600 and I cut out the black one in the back it was the 0.2 and replaced it with a new 0.022/630.

Yeah Just Radios sent me the 470/15KV's in the mail today that they messed up on. I am not sure if I can get into that HV cage without removing the CRT.
Could I just skip those... if I do not want to remove the CRT from the chassis?
Fire it up to see what I get?

I believe that the bright red one at the top is C172 on the Sylvania schematic. It is probably o.k. I'm not sure what it's made of. I have a bunch. Maybe I should cut one open to find out.

Did you really replace the 0.2 with a 0.022/630 or was that a typo?

Curiously, in the second production run they replaced the 0.2uF paper capacitor with two 0.1uF paper capacitors in parallel. Finding a 0.2uF at 600V might have become difficult. Otherwise I can't see a reason for it.

All I can say about the HV caps is that the same exact part number in my Sylvania was bad. I don't blame you for not wanting to mess with the CRT. I don't think it would hurt the flyback. But, I'm not sure.
