Default Re: Bush Dual standard chassis.

I'm confident they are the same.

Rank Bush Murphy did also use an alternative and functionally equivalent LOPT for the TV125/TV135/TV135R/TV135L models (plus the 23" sets and the Murphy equivalents), which was made by Plessey Windings.

The difference being that the Plessey LOPT didn't use the (black) pitch encapsulation. Instead, the EHT overwind had a coloured plastic outer cover (usually red or grey) and the primary windings had a translucent resin covering. There was also a coupling winding on the EHT overwind side, that was would on a fairly thin plastic bobbin.
