Problem Toei Chassis/Tube Swap

[benimaru7]

Hi mate, I’ve got a Neo 25 with Hitachi tube, I’ll check what yoke it has. Believe it’s the Toei chassis

Cool beni thanks

I’m not so sure. I think this is just the reality of using the original Toei yoke as it seems others had the same symptoms when trying this.

Yeh …
Or could it be bad pin cusion?

Bad cap in that local would
Cause that symptom.

Did others have bad pin ?
Or bad horizontal width ?

You able to identify those caps? I’ll swap them out if so but I’m hopeless at diagnostics as you can tell!

You need the schematic

Pin curcuit should be next to horizontal deflection circuit..

I will if I get time later look for that cap , but it could be the mossfet also shorted , I’m just trouble shooting it .

It seems you have no pin what so ever .. by the looks of that picture.

I would look to be trying to solve that .

you really could do with the inductance and impedance readings of the yoke

I’ll get these readings. I need to get a meter to measure inductance

If it’s same yoke as mine
Should be same readings as mine ,

Looking forward to your yoke readings 👍
