Paper caps need changing, the 3A2 is only rated for 18KV so it is not a good choice for HV rect in that retrofit, and also why did you move the damper inside the HV cage?

[Tomcomm]

Not to worry,Tom. That was an early iteration, the only good photo I had.
The HV rectifier is a 3A3 in the pix not a 3A2, you had that wrong. As for the paper caps....I don't replace stuff that works. Whats your hang up on the damper? It was mounted with the CTC 20 FBT for convenience.

Get a life, this thing has been running off and on for 8 years now with no failures. This 21CT55 is the only tube TV I've got. We've grown old together.

The HV rectifiers shown in that pic ARE 3A2s...3A2s are 9-pin minature types 3A3s are bakelite base octals there is no mistaking what is pictured. You may have 3A3s in it now but when you took that pic there were 3A2s in it.

By that logic I assume you are still running 60's vintage Valvoline oil in your Olds Healy...Running paper dielectric caps in a TV these days is about the same as taking a barn find car that hasn't had a fluid change in 60 years and running the original fluids till it ceases or the engine block cracks...Actually, you already experienced the TV equivalent when you burnt up your flyback some years ago.

Well you can close the HV cage and hide the new damper, but it still will look weird if the old socket is empty, and you or anyone servicing the set in the future could plug the yoke into the wrong scoket by mistake.

If my opinion on your posts is unwelcome I'm perfectly content to let you continue to publicly talk to yourself (as you primarily have been in this thread) mindlessly reposting old pictures we've already seen and repeatedly asking an uninterested pack of crickets for a response...Shine on ya crazy diamond-Pink Floyd

How many Videokarma members see 3A3 rectifiers in my photo postings?
Actually I used CTC-20 3A3A hi voltage and 3A2 focus.

Tom's comments about "paper capacitors" was a matter of his preference.
His OldsHealey comment refers to my life's major hoby project that is still
competitive with Shelby's 427 Cobra! What might his life's magor project be?

As for Tom's rag about my repeated posting various shared photos was
mindless and completely unfair. I was attempting to find a replacement
for Photo Bucket photo sharing. Sorry for anyone's inconvenience.

The winters must be pretty long and cold in Pewaukee/Delafield to keep
Tom entertained, eh...........Tom

[Tomcomm]

Apart from all the noise, does any member know of a successful flyback transformer
transplant actually performed on an original 21CT55 with a much later donor
flyback system install? Just curious........... Mindless Tomcomm

Actually I used CTC-20 3A3A hi voltage and 2AV2 focus, both are backlite
based octals that were pretty obvious in the photo.

The only octals in that photo in the HV cage are the damper and HV regulator...Look at it closer.

Replacing ALL paper capacitors: the 'preference' of >90% of all TV and radio collectors who repair their equipment....If cooking the original flyback didn't teach you a lesson I suppose nothing I (an ELectrical Engineer) or others in past threads say will ever get through to you.

Would you agree that facts are fair? Going back through this thread you've been trying to "find a replacement for Photo Bucket" since 11-10-2017 and have made over 70 posts to that end in that time... I just created a new flickr account (since my old one was full) in 10 minutes and confirmed it works with an edit to one post...Comparatively speaking is it not something of a joke to take what ammounts to 1.3 years and over 70 posts and STILL not be done with the same task I just did in 10min?

It was 54 here today and there are a variety of things inside and out I could better spend my time on than trying to show you reality.

[mrjukebox160]

I sharpened and expanded part of your photo. It is a 3A2.

[Tomcomm]

After much confusion I have identified my infamous 21CT55 photo as a very
early work in progress attempt to replace its FBT. I agree that both CRT
anode and focus rectifiers in the photo are 3A2's, dated Dec 19, 2010.
The original 21CT55 uses 2 3A2 in a voltage doubler HV CRT anode circuit.

The latest FBT replacement photo, dated July 5, 2011 clearly shows the
focus rectifier as a 3A2 mini, and the CRT anode is clearly a 3A3C octal.

Apparently my 21CT55/ CTC 20A hybrid still uses this scheme today, Feb 3, 2019.
Too bad there was so much vicious discussion. I don't do well with bullies.

All I have to say about it ( never having seen that model before, and not wanting to get into the fray ) , that at first glance, it kinda reminds me of the set of a Frankenstein movie, if looked at very close up!

Be aware if you hadn't insulted me with that "get a life" quip in response to fair critique of the state of the set in the pic you would have gotten a much flatter response there after. I'm no bully, but when someone randomnly slaps me in the face I feel strongly inclined to return the favor...

How to post a pic from flickr to VK: Go to the album, photostream or gallery the pic you wish to post resides in and click said picture. (Pro tip: this whole process should work for your own account as well as in some other people's accounts.)

Once on the page dedicated to said photo click on the share arrow in the bottom right corner of the black space.

Once the popup box opens:
#1: Click the BB code tab (if there is no blue bar under it) to get the blue bar under it. The blue bar indicates which tab is selected.
#2: click the size bar and menu 3 opens to allow you to select the size you want it to display in here on VK.
#3: pick your size (I've highlited some good choices)
#4: click the BB code bar, the code should turn blue, copy it (using CTRL+C keys or by right-clicking and selecting copy from the menu that appears).
If the pop up opens in the BB code tab at the size you want then you can skip steps #1-3


Now go to videokarma (which you presumably have open in another tab of your web browser so you can quickly switch between VK and flickr tabs to quickly post multiple photos) and paste the BB code in the thread where you want it.

You can even remove a snippet of the end of the BB code to suppress the user accredidation links. (click quote on my post and examine the text comparing the second and third pic to see how I did it) I like to do this when I post a gallery of 320X240 shots...I can arrange the edited BB code pics in a nice neat grid of mid size thumbnails that is still clickable to access the full size pic on flickr.

BTW: you don't have to actually post to check if your photo works. You can click the go advanced link under the reply box on VK write up a post insert the BB code then click preview to see a preview of what it will look like (photos and all)...You can edit it further if you dislike it and re-preview it if you wish, or click submit to post for the world to see. This is a great sandbox to test stuff in without showing the world that your fumbling with making pictures embed in your posts.
You could also go to one of your old posts and click edit and add pics to an old post (just remember VK has a pics per post limit of IIRC 16).



Advanced warning: Since IIRC each account can only hold 2K photos now once I start to run low on space in ~1-3 years I'll delete the photos in this post from my account and they will cease to exist.

Another way that just gets the image address without the added text and links:

On Flickr, click on the download arrow at the far right bottom.
A popup menu appears with several sizes and "View all sizes."
Click on "View all sizes".
This brings up a page with all available sizes listed.
Pick the size you want and click on it. When that image appears, right click on the image and select "copy image address" from the pop-up menu.

Back at your VK reply, click "Go Advanced"
Above the text box, click the "insert image" icon (looks like a postcard of a mountain).
In the popup for the URL, paste the image address that you copied from flickr by typing CTL-V, and click OK.

EDIT: incase you were in doubt, neither procedure actually copies the image to VK, only the link. Therefore, you must keep the image on Flickr or it will disappear here too.
