Also Neck boards for 12 pin and 8 pin TV CRTs are on the cards.
I would like to make generic Deflection Yokes for color Tubes. They will be made from the yoke that comes with the TV.

This will be my next experiment.

I will make neck boards for 8 pin tubes and 12 pin tubes, so almost any tube can be a vector monitor

Join in the discussion if you want

(EDIT: This allows more tubes to work off my type of repro HV board) I guess you could adapt the original type if you wanted

This would be cool. I'd be specifically interested in a rewound yoke designed to fit the tubes used in 25" WG K7000 monitors. They're plentiful and used a medium resolution tube (although the monitor itself was standard). Just about anyone can get their hands on one of these and rewind the yoke for an Amp set up. You could use the 19" K7000s as well.
 
un-wound the large Gottlieb System 1 pinball transformer and counted the revolutions. the wire was expensive
wound it back up and it worked !
except for the large buzzings sounds, it powered the pin !

got nervous and found a cheap working one on ebay and installed that one instead. sold the pin and didnt want to take the chance of a fire or anything else bad happening

now i have all this wire...
 
More CRT connectors are on the way for 8 pin and 12 pin tubes. (The white CRT bit)

I have some Neck PCBs left over from the HV board project (The green PCB that is), so they could be used easily enough.


If I make the 8 pin neck boards with the same pinouts then any compatible tube can be used on the Amp setup

When I wound the little T1 transormers I was worried, I admit. But it's pretty straight forward, if you wind it the same it should work the same.

The buzzing is probably a short circuit within, either to another winding or the frame.
 
The Amplifone plant in Texas would have simply had a winding rig. Can you replicate that somehow?

Another question - if you made a yoke to go between the 6100/Amp electronics and a standard CR31 tube you can find anywhere, would you be able to compensate for pincussion, etc..?

Can do, we could look at that later, also, I don't want to step on people toes, who may be looking into pincushion correction already

I will look into the similarities of the different horizontal yoke magnetic cores. If the brands are close enough to each other I can make a rig.

The T1 rig eventually got motorized as you may have once suggested. It has a speed control so I could ramp it up slowly and finish slowly. T1's took about 3 minutes for 400+ turns on the primary side.

I could easily adapt the rig for Yoke cores

Each yoke is really matched to it's own Tube in an ideal world.

However . . . I have enough different tubes here (About 15, I guess) to experiment and see if they're interchangeable - That would be nice :)

The most common tube that I've found in 90s 19" tvs is the CR31 "thin" neck tube. A yoke to fit that would be nice..
 
and I think I meant CR23..well crap, it's usually one or the other, except for the one CR24 110deg tube I found..

I just read the book for this HERE

Can you please tell me the tube part number. First we need to see if they are vaguely compatible

Cheers

A lot of these monitors are already pin compatible

See spreadsheet. I have a full set of sencore adapters so can easily work out what pins do what etc

This is some of the A63 Tubes for example. Its an excel spreadsheet comparing BK adapter numbers with Sencore adapters.

There are a lot of tubes that would work without adapters though
