Fradan Radio. All band 'Comet' Radio

A two valve radio kit from 1963 using the 1T4 valve. Designed as a beginners radio and marketed by Fradan Radio of Leigh Lancashire. A conventional circuit that can be built as a one valver and then expanded by the addition of another 1T4 stage of amplification.
In 1963 the 1T4 (DF91) valve was obsolete by nearly 10 years so this set by a little known company was probably just an attempt to get rid of some obsolete valves.
