let's discuss CRT TV ownership

[matt]

Got this bigboi for $100 yesterday for my buddy who is building an arcade cabinet.

i'm eyeing a similar panasonic that I could get for 5 dollars. 27 inches still makes me doubt though.

@“matt”#p158676 Panasonic gang. Panasonic rules. Was known as NATIONAL brand in Japan.

@“treefroggy”#p158696 Interestingly, Panasonic/Matsushita in Australia was known as National until 1988 when they changed the name to Panasonic.

What is the safe distance between a CRT and unshielded speakers? I've seen anywhere from 12 to 36 inches. Thanks!

@“Naaaaaaaathan”#p159536 I do a couple feet personally. not taking any chances. the median of the two numbers you posted hehe

@“Naaaaaaaathan”#p159536 Definitely have the TV turned on when placing the speakers. If it's turned off then the TV degauss on power up will calibrate to the magnetic field around it, essentially making the speakers a part of the magnetic deflection field. If you were to then move the speakers away, the TV would be discolored.

I'd recommend:

- Turn the TV on

- use a [240p test suite](https://artemiourbina.itch.io/240p-test-suite/purchase) and make the screen pure red (or switch between red, green, and blue and look for impurities while positioning)

- slowly place a speaker closer to the TV where you think it is safe ( fyi, bigger speakers = bigger magnets = bigger area of effect)

- if you notice any discoloration when placing the speakers, then move away it quickly (discoloration should clear)

- a power cycle will deguass and should clear any recent discoloration that won't clear

- you must wait a few minutes between power cycles (keeping the set off) for the deguass to cool off so it will trigger again on the next power on

For normal bookshelf speakers 3ft away should be good. A subwoofer that's not shielded should be as far as possible.

Good luck!

@“copySave”#p159871 Thanks for the advice! I ended up at 26 inches just to be safe.

I have the top loader NES running into the tv and out to a mixer from the headphone jack. SNES is directly into the mixer. Been blasting Chrono Trigger Sound Library and NES sound tests. It is great!

took a photo of outrun when i remembered there was a MiSTer core for it

cool vintage shop this weekend

[powderooze]

Almost didn’t fit in the car. Phew.

No TVs or electronics at all in this cabin we’re staying in Twin Peaks, CA. Which is good. I brought my CRT and super famicom so I can watch my gf beat donkey Kong cuntry 2. Love to be in a house where the only display is a crt again.

Though there is a dirth of proper furni. No hardwood to speak of, just annoying stuff from target and a couple nightstands.

I got this guy for 20 bucks on the Austrian Craigslist and the guy even delivered it to me with his car. :)

[homso]

found this ol’ Burle security monitor at a thrift store for $22!!

it’s only composite but on such a small display i think it looks quite nice! surprisingly the tube is still pretty bright and there’s no burn in! there is some mild bowing on the sides but i don’t know how one would adjust this without opening it up. either way, i’m happy with it as is!

[antillese]

The perfect test game. Looks incredible!

[treefroggy]

You can begin a google image search by typing “CRT Room” and explore around, I found some pretty cool and classic setups that way, like non-gaming, non-gamer setups, since imho the crt rooms of gamers tend to be maximalist in less aesthetically pleasing way than say, a hotel room that still has a CRT as its centerpiece.

[treefroggy]

Hell yeah that’s just like the security monitor I found at the Pool Maintenance job I had, and I used it to play final fantasy vii that summer cause I was in the middle of a 90 hour play through in my van before the remake released.

I have done my own trichromatic test taking photos of my tv. We’ll see if Frank is no longer the only one with a perfect picture!!! (after I take the rest of these photos and then wait a week to have them developed)

[homso]

So I opened up that security monitor I found see what’s going on inside. as it turns out the monitor is a rebranded JVC!! I examined the tube and from my digging it looks to be all but identical to the TM-1400U—except without speakers. It even seems to have latent S-video capabilities (from the slightly higher end, S-Video capable JVC 1400SU) wired to the outputs but without ports included. I’m wondering if it could be a relatively straightforward process to re-enable the S-Video with a mod. There is a plethora of information regarding RGB mods but S-Video doesn’t get nearly the same attention. Based on the service manual for the tv and the datasheet for the jungle chip it looks like it’s definitely possible to patch input into the luma and chroma but I’m not entirely sure what the best method would be to go about this. Looks like more research is in order!
