If you would like to become a Patron: www.patreon.com/spatsandharley --------------------------------------------------------- Chassis serial #B8002795, cabinet #759. After owning this TV for nearly 6 years now, I am finally getting around to the restoration of the RCA CT-100. Due to the complexity of it, I plan on doing videos of its restoration in numerous parts to document everything I do on it until completion. This video was done on 3/24/19

What were you guys watching? I heard the audio coming from the CT-100 speaker

so far i'm really enjoying the channel and the content it produces, really nice to see a television that isn't seen very often on youtube getting restored, i think that when it's all done you'll have the only video of a working ctc-100 on youtube, great work, keep it up. on another bit; what are y'all's thoughts on those sony trinitrons, to be more specific the ones from the 1980's. and would y'all know anybody who maybe knows how to fix them or maybe teach me some stuff about them, as i'd really love to learn these sets and get my 83' console back to (even better) working condition. i mean, i'd assume that Emmerson Collie would know about the sony sets as i've seen a few videos on his channel of the things, mainly that legendary videoscope model, overall i'd really enjoy speaking with y'all and maybe learning some stuff. this comment was really.. disorganized to say the least, but still. point is i really enjoy the content and am quite happy to have found a community that seems to have all of my hobbies concentrated into one place.

It’s still being worked on...

Hey Spats, did you ever get your 1982 Magnavox (Rebadged Panasonic) VHS top loader fixed?
Trance88 (2 months ago)
Fantastic progress, you guys!! Eeee!! I'm getting excited!

You are doing such a great job with this restoration.

Great Video as Usual. Can't Wait Until The Next One. Also Can't wait for another road trip video in the Chrysler New Yorker.

This was so exciting... the quality of sound from that speaker is excellent!

What no Dr. Frankenstein, It'sAlive, It'sAlive! :) Seriously though, that is very awesome to see it coming back to life,the Main B+ seems very good, the RF and IF decks appear to be in reasonable alignment and the detector, as well as the amp, are working well (and since it'san RCA, and not a Zenith "Buzz-O-Matic" the audio will be good, with the exception of screens of text). Nice to see the Horizontal deflection and the HV come up nicely. I did not hear the vertical deflection (normally the vertical output transformer makes quite a distinct sound in these tube based sets) so you will want to be careful and start the set on reduced brightness when the CRT is installed, the last thing you want to do is to burn a line into that CRT. Do not worry about the HV voltage until the CRT is installed. The failure of the convergence transformers on these sets is a lot like the failure on the later Tektronix 547 HV transformers(the first tones where potted in beeswax and are fine), as the potting epoxy becomes hygroscopic and causes the transformer to fail. In the Tek, when that happens in the CT-100 it will take out several parts including the unobtanium focus control.

@Harley Badger - from Spats & Harley That's a bummer, but at least those transformers had substitutes If it is the Vertical Output, Stancor A-8145, Merit A-3038, Triad A-107X or Thordarson 26S53, and the only change needed is to drill a new mounting hole.

Welp... good call on the vertical deflection. VD transformer is shot.

@12:56, what in the world is that awful noise??
Maxxarcade (3 months ago)
What was the little "clink" sound at 6:59? Stuff like that always makes me nervous when working with fragile CRT's.
Spats Bear (3 months ago)
It was Harley, he bumped a metal stand right behind me.
Emerson Collie (3 months ago)
It's going to look, and turn on like brand new once it's all done. And to think that a few old farts in the vintage TV world doubted you. lol
Terry McKean (3 months ago)
Right on Spats and Harley.... awesome work-in-progress. When the CRT is in place it will add capacitance to the HV circuit and increase and stabilize the HV.

Wow this channel has both of my favourite things furries and old tv repair
Trance88 (2 months ago)
As odd as it sounds, Furries and vintage electronics seem to go hand in hand! So many furs I know are into vintage electronics, cars, decor. Heck, I have Spats to partially blame me for becoming a fur!

Always get a little nervous when you push the camera in to shoot a closeup of the CRT neck and up over the top to the pins. Lol. I'm sure your meticulous attention to detail will be rewarded when you do your power up w/CRT installed. Also, looking forward to the cabinet refinishing video.

Very nice! The audio is quite impressive! I've got a feeling this will be well worth the restoration effort.

enjoyed it Harley and Spats! : )

Thank you!

Pretty cool and exciting to see it coming back to life. Great job.

For the degaussing coil, you'll definitely want to rig up a makeshift winding jig. Perhaps something like a garden hose reel wrapped in cardboard to get the right inner diameter? Put the supply spool on a peg so it can spin freely as you go. As long as you are gentle and get the angle right, you'll get a nice tight wind, and follow up with some strips of Kapton tape or similar to keep it bundled during handling, and finish off from there.
Harley Badger - from Spats & Harley (3 months ago)
@Maxxarcade Yup, we need exactly 1150 feet of 26-gauge magnet wire. Fortunately, the spool we ordered is about a hundred feet too much, so we're just gonna wind off a hundred feet and use the rest of the spool.
Maxxarcade (3 months ago)
@Harley Badger - from Spats & Harley I bet it's gonna be really satisfying to fix that coil and get the CRT mounted back in the cabinet where it's safe. Do you have a way to measure how many feet you've wound? I know the wire spool jigs at hardware stores have a roller setup with a foot counter. But it'll sure be easier than winding by hand either way LOL.
Harley Badger - from Spats & Harley (3 months ago)
Ooh! he didn't mention it in the video, but I invented a winding jig. #GoHarley!

OMG when I heard that rich sound coming from that speaker... It wasn't even mounted in the cabinet yet! And it's very encouraging to see the HV running. And having a possibly rebuilt CRT is the ultimate icing on the cake. Beautiful cabinet so far too! This thing is gonna be epic :-)
kraig 88 (3 months ago)
@Emerson Collie, you're right dude. I cant wait until this is done. However, it's going to be worth the weight.
Emerson Collie (3 months ago)
Yeah, I was thinking the same. That speaker sounded great as is, outside the cabinet. It's going to sound even better in the cabinet.
