BUSH I.F. TRANSFORMER PROBLEMS
This type of IF transformer, which was used in many of the early Bush radios, has an inherent problem – the dust iron cores either break or become detached from the brass adjustment studs. Removing the transformer from the aluminum can is bad enough, and effecting a repair is a lengthy process and quite a fiddle. I use Araldite to glue the cores onto the brass studs. Obviously, they must be perfectly lined up and held in place while the glue sets.
