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......
This is a Marconi MF/HF communication receiver type AD108 (inst No 377629).
The Modes of operation are CW, MCW, RT. So Keyed-Carrier. Modulated Keyed-Carrier or AM.
Supply is from the aircraft 24V DC supply giving 19V (LT Supplies) 24v / 250V HT dc.
There is a really nice enamel Marconi badge on the lower-front.
------------------------------------------------------------------
Unit is about 14 inches deep, four inches wide, and 8 inches high
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.
