Speakers Philips BCA405A and BX626A (Algemeen)
Dear friends
1. BCA405A
This radio set is identical to BX405A. May be it was assembled in India.There is no separate manual for BCA405A. In the service manual of BX405A the type of speaker mentioned is 9738X but in the BCA405A set the code given is 49.239.72. This speaker is different from 9738X.
2. BX626A
Here also the service manual mentions the type of speaker as 9770. But in the set which I am restoring the code no given is 49.239.94 and this is different from type 9770.
I am attaching the photos of the two speakers. Are some details available for the above two speakers?
Regards

I don't know what "F" stands for, but
Y = "Notably higher response level in the region 2 to 6 kHz"
X = "Same as Y, but a wider frequency range"
In radio's with extended short wave bands you often find "X" type speakers, i think because these radio's where often used to listen to speech.
I studied a few service documentations and found for the BX type radio's from the early 50's to about '52-'53 they have speakers that where "repairable". Sometimes only parts where available, not complete speakers. In that case the speaker seems to be a part that was specially made for internal production for radio's only, which COULD explain why there is only a codenumber on your speakers.
From about '52 -'53 the sevice docs mention "not repairable speaker" which means the complete speaker must have been available at least for service purpose.
Maarten Bakker, also a member of this forum is known to know VERY much about Philips codenumbers. Maybe he can spread some more light about this numbers?
