Mullard RF/IF and audio modules had quite a run of popularity and were incorporated into many radios - partcularly, though not exclusively, Roberts. As many restorers will know, the modules used the now infamous AFxxx range of silicon transistors, prone to failure. At the links below there is comprehensive data on these modules - two 38 page and 46 page PDF documents (700kB & 800kB) which may prove useful in attempting any repairs:
http://www.electrojumble.org.uk/DATA/Mul...5-1174.pdf (38 pages).
http://www.electrojumble.org.uk/DATA/Mul...0-1402.pdf (46 pages)
All sorts of other technical data can be found on the same site at this link:
http://www.electrojumble.org.uk/techdata...conductors
The site is run by an enthusistic amateur - not a full time business as such, and he has lots of useful items for sale - connectors, valves, bulbs, fuses and so on. The home page (recently updated) is here:

Hope that's of interest to someone.
