BlueBookGuy Posted March 21, 2014 Share #26 Posted March 21, 2014 ...never seen before such a thing .. the fact of a PL-55 marked plug shows clearly it's a AAF-made item. The PL-179 male terminal was for a direct plugging into the radio set, as it was fot the British-made radios. Many modifications including this one, were made to AAF fighter planes operating from England (just sold out one of these T-44 assemblies a few days ago).

BlueBookGuy Posted March 21, 2014 Share #28 Posted March 21, 2014 interesting! Will have to go searching for this - do not understand why that PL-55 plug, at the opposite end from that other large connector. Maybe someone else on the Forum could have any answer?!? Franco.

littlebuddy Posted March 21, 2014 Share #29 Posted March 21, 2014 The large plug is the "female part " of the RAF bell Type plug Franco ,if that helps ?? Link to comment Share on other sites More sharing options...
manayunkman Posted March 21, 2014 Share #30 Posted March 21, 2014 Very nice set ups. Thanks for posting it. Link to comment Share on other sites More sharing options...
BlueBookGuy Posted March 21, 2014 Share #31 Posted March 21, 2014 If so, thus the PL-179 plug (RAF-style) didn't go directly into the aircraft setup - as I instead read in many a text. At this point, must think: the PL-179 plug (already in itself a good convenience being a single unit, for both helmet and mask's cables) connected into its female counterpart, wich definitely stayed inside the cockpit. At the other end was the PL-55, wich plugged into the radio box in the same way would have done the standard AAF helmet's extension cord. Pilots exiting the cockpits simply pulled out the large PL-179, and those much shorter adapters stayed inside. The only answer in my opinion ?? Franco.

Blue Leader Posted March 24, 2014 Author Share #32 Posted March 24, 2014 Hi, The cord CD-176 allow the use of the microphone T-44 or MC-233 only, not the earphones. It is the equivalent without the switch (SW-141) of the cords CD-318 and CD-508 used with the T-30 micophone (PL-291). The PL-55 jack is designed to be plugged on an US transmitter, the PL-54 and PL-354 jacks to the receiver depending the impedence. Mathieu Link to comment Share on other sites More sharing options...

Blue Leader Posted March 24, 2014 Author Share #34 Posted March 24, 2014 Hi Carl, Read CD-716 and not CD-176 This adaptor stayed inside the cockpit plugged into the radio box of the SCR-274N radio set for exemple (here in a P-38). You can find a british version of the CD-716 with the british female plug and an equivalent of the PL-55 plug, in red with the AM marks stamped on it. I think it is for RAF pilots flying in american aircraft like P-40 or P-38 ... A+ Mathieu Link to comment Share on other sites More sharing options...
littlebuddy Posted March 24, 2014 Share #35 Posted March 24, 2014 So could this cord be used for a RAF c type helmet with Raf receivers and a type A14 mask with mic to be used in an USAAF aircraft ?? Link to comment Share on other sites More sharing options...

The CD-716 allows to use the earphones and not the microphone. It is the equivalent of the extension cord CD-307. It is the PL-68 plug which equips the US microphones. So, yes you can use it with a RAF C type helmet with RAF receivers and a type A14 mask. A+ Mathieu Link to comment Share on other sites More sharing options...
littlebuddy Posted March 24, 2014 Share #37 Posted March 24, 2014 Thank you Mathieu for your help in sorting this out for me !! Carl Link to comment Share on other sites More sharing options...
Nigel.R Posted March 24, 2014 Share #38 Posted March 24, 2014 Carl the C type would have to have either a standard RAF loom or the 2186 series parallel though as we talked about in order to use the Bell plug . Link to comment Share on other sites More sharing options...
