The Design

This is an early prototype of the successful Taslisman series. The later ones (like this 306U Talisman) has circular MF transformers while this one has square ones. There are a few more technical differences (in parts used) but the most striking is that this one has a slide rule dial, while the later models all have a rotating pointer.

This Object

With the small Teslas I always seem to have a common problem: hum, despite replacement of capacitors, and bad sensitivity.
