Current stock of Transformers, Ferrites, Coils etc:
Transformers. The following transformers mostly have high voltage
windings, Suitable maily for valve power amplifiers etc. They are
mostly used, and quite old. They represent a range of transformers
that would be hard to obtain today and may be of interest to radio
amateurs, of for restoration of valve equipment. They are all
heavy, so are most suitable for collection (by appointment). No
prices are given, all open to offers:
