(16-Nov-2002... Updated 05-05-2019)
At the bottom of this page you will find an info-sheet and service manual
for the Marconi AD108 Reciever. ALSO I have just obtained another of
these receivers, so I'll get more pictures and info up here soon......

There is a really nice enamel Marconi badge on the lower-front.

If I had to put a date on it's manufacture I'd say mid 1950's
A rotary-converter lives on the rear upper part of the case to
produce the 250v HT DC voltage from a 24V DC supply.
