Ferranti inter valve transformer repair.

[Yorkie]

An excellent thread Colin - very informative on the challenges you've faced, and how you overcame them, remembering of course that your first major coil winding challenge was to restore the Avo winder to working condition, with all that entailed. Yet another example of your fathomless propensity to take on seemingly impossible tasks, and to see the job through to a successful conclusion!
