[R-390] Audio output transformer

[Dan Merz]

Hi,  much thanks for posting this process.  I've rewound many audio
transformers for old battery radios but never figured out how to make the
core without the end bobbin supports as a permanent part of the core.  I
typically glued up pvc or polystyrene and left the end pieces on - which
takes up space.  Your process of holding the end pieces in place was
enlightening.   Nice job and thanks for sharing the details,  best regards,
Dan
