Hanterex chassis to tv tube

[Retroman839]

Both should work. Some can show higher output with no load. 139v is within the MTC900/E's tolerance though, it can take a maximum of 141v according to the service manual.

Ok … cool ..


It flutters around 140 & 139v



How much voltage drop
Would a mtc900/E Cause ?

I need to make a rgb G s vídeo source connection next

But I could just get a raster up for now
I will try tomorrow

Hi ya mate ,
Yes Thats is the one ..Thanks
I have it here ,, and hope to get it wired up tomorow 👍

I didn’t get any leads in the box ?

 

[Retroman839]

I need to put female spade end on dag kneck ground

Get a connector for yoke wires

And rgb connector also ..

 

[Retroman839]

Do middle 2 pins on 6 pin yoke connector need to be linked ?

 

[tb2000]

Yep, the 126v B+ runs through it, it's basically used as a safety measure to stop the chassis being powered up without the yoke connected.

 

[Retroman839]

Ok ..
Chassis is now ready to test
Except main fuse has corrosion inside it and outside it ,,
What type fuse for this ?

 

[gunblade]

thats a time delay fuse

 

[Retroman839]

thats a time delay fuse

Thank you grant
I will consult manual
I see 2A or a 3.15A

 

[gunblade]

what position is it?

 

[Retroman839]

Good question ..
I’m not with chassis ..
Right now só will comsult
Schematic.

it’s the first one right on the live input.

F1 I guess

 

[Retroman839]

That isn’t helping me so I will go check it out

 

[Retroman839]

I’m worried all the corrosion inside fuse will cause it to blow

 

[gunblade]

i replace the fuse holder as well when you see this sort of corrosion but for testing purposes you can get away with both if you clean them, bit of wire wool will do the job

Will do that then for now.
Ta…
Then put a clean holder in ..
I will order both types
And check if
I have that type
2A
And 3A
Time delay

I'm sure I cleaned all that off it before I sent it. Whatever the case, it was definitely working fine. You could gently clean the fuse ends with a fibreglass pen or bit of fine sandpaper etc. If you want to replace the fuse, it might be worth also gently bending in the contacts of the fuse holder toward each other a bit to make sure of a good contact.

will do that thanks ..
( my fault keeping it in box for this long )

Hey man ..
I am at a critical point
Hori/ vertical windings ..

I have been on phone to swallow this morning for all parts for yoke & rgb connector to assemble correctly ,
But as i am a bit impatient
I am all connected ..

However ..
I don’t know my hori from my vert wires!

Have a look

We got red /white & yellow/green .


Then
Chassis side I have


Yellow/ green to red /green

Blue /brown to red /white

Am I hori to hori

Or am I wrong ?
And need to swap hori & vert around. Thnx 👍

You need to get a multimeter, put it on the ohms setting and measure each pair or wires that's connected to the yoke to find out which pair are for the horizontal winding and which pair are the vertical winding. At a guess i'd say the yellow and green are the vertical and red and white are the horizontal going by how they're soldered on, but definitely check first using the multimeter. Horizontal should be between 2.5 to 4 ohms. Vertical between 12-15ohms. In your picture of the chassis with the connector on the chassis yoke socket, green and red is the horizontal, blue and brown is the vertical. So it looks like you need to change some wires round. Double check and don't get them mixed up or it'll damage the chassis and/or the yoke!

 

[Retroman839]

I got meter with me ..
Will check in a sec.
Big thnaks

 

[tb2000]

Once it's connected up, double check it's right by probing the yoke plug.

 

[Retroman839]

Só yeh I’m cross wired !

I will swap em round
