Hanterex chassis to tv tube

[Retroman839]

🙏😊🥰
It’s very nice thank you
one tiny bit of high pitch for one second then silence ..



Jamma loom & psu going in

And this is now coming in doors ..
massive thanks man

Glad to see it working! The second or so of high pitch at power up was probably just the linearity coil, nothing to worry about.

Very happy mate
No magic smoke 👍😊

I have a black stripe tosh tube next ..


Shall I start a new thread
With yooe measuemts

That a 20" or 14" tube? Difficult to tell from the back! 8 pin minineck tube so if you've not got a chassis for it you'll want a WG K7000 or Hanty with the 8 pin neckboard. A Hanty with the 8 pin neckboard socket is rarer than the K7000 unless you go with a Polo 2 or Polo 3 chassis. I don't think i've ever seen anything pre-Polo chassis with an 8 pin neckboard socket apart from the 10 inch MTC900, MTC900/E and MTC9000 versions.

It’s 20”
A51

I might have chassis for this
Not sure if they work though

 

[Retroman839]

I disconnected everything
Removed tube & Chasis from cab

Reconnected and I connected 110v to the demag ?

Now i have 110v to the power input rather than the demag ..

I do not have demag connected yet ..

Do I take 240 live & neutural from primary of the iso transformer ?

Can I bring this back ?

I have the dodgy green demag tool .

 

[Retroman839]

God bless the magic geeen wand 😊
I’m all good it’s now in my games room 👍

 

[tb2000]

The degauss circuit wires need connecting to 240v. It won't work properly on 120v. You can link to the primary side of the isolation transformer. It shouldn't really matter as far as live and neutral goes but i'd still connect the live to the fused side of the circuit. It should then automattically degauss the crt at power up.

Live to fuse ..
That’s what the second fuse is for then !
Got it thanks ..

I will look for 8 pin kneck Hanty chassis for the tosh blackstripe
Tube

 

[Retroman839]

Nah I don’t have any 8 pin mini kneck …
You got any ?

 

[tb2000]

I have indeed. I can't sort it straight away as I have a number of other chassis I have to fix up first but i'm sure I can sort something out. I have some 8 pin neck WG K7000 chassis. I might also have a Polo 1 minineck chassis, a Polo 2 15khz minineck (can't remember if i've already sold it) and got a number of Polo 3 and also M.E.S. (Monitor Electronic Systems) chassis with 8 pin neckboards.

 

[Retroman839]

No rush mate
When your ready 👍
15khz polo 1 would be my preferd choice …
Should be nice apparently
Tosh black stripe was Toshiba answer to Sony trinitron tube ..
Upped contrast and sharpness so what ever chassis you think will do the tube justice pls mate

 

[Retroman839]

Going to sort all power on cab today so one iec kettle shocket fused feeds a 4 way multi gang through emi filter to the ttansformer .

 

[Retroman839]

Been on for 2/3 hours
I’m getting a bit of green overdrive

But then it settles down just and goes back to normal
But I get a flicker every now and then like it’s going to go into overdrive again ? CAP on the kneck .. bad pot ?
The colour pots — I will try to turn em tomo when cab is off but tried but they didn’t want to turn tonight ..
Only over drives for 5-10 seconds then goes back to normal .

 

[tb2000]

If it only flickers full green it could be an iffy cutoff/gain neckboard pot in the green circuit, if not than an iffy BF871 (or BC547) on the neckboard in the green circuit. Or one of the small signal transistors (BC547 and BC557) in the green circuit on the rgb interface part of the chassis. I wouldn't have seen that unfortunately as I usually tend to test these chassis for 30 minutes to an hour. Problem is, that's the kind of colour fault that can take hours to work out if you've fixed it! Only way to be 100% sure really is to swap all cutoff/gain pots, BF871's, BC547's and BC557's for new ones.

I will sniff it out ..
The pots look a bit tired
What s good replacement ?
I have a few I might have some that are the correct value ..

I will try something other than pandoras box as I might have gain up to much

Try and use proper Piher (or equivalent) vertical pots for the neckboard, they're all 470ohm. Also, I can't remember exactly what type of transistors it's got but it could have BC237 instead of BC547 and BC307 instead of BC557. BC237 and BC547 are interchangable though as are BC307 and BC557.

Thanks I will look at getting
Pots for it 👍
