Default Re: PYE LV20/B18T 1948. Heart transplant.

Here's a very crudely executed heart transplant which was done almost twenty years ago to my Sobell T121.
Can anyone identify the line output transformer? A Mullard BY182 is used to replace the EY51 EHT rectifier.
Different scan coils were used to match the replacement line output transformer which in turn necessitated replacement of the frame output transformer.
The Sobell performs very well considering the simplicity of the circuit design.
Same chassis was fitted in the Columbia C501.
