C243N (C243N) and B830B 

Hello,

C243N from 1934 it is wrong.

I have copy of original Philips service document for the 830B dated from 1932.

The reference to 1934 is linked to the change of codification made in 1934 by Philips, C means 200mA AC/DC type, the C243N is a 2V battery tube, following the previous codification.

Best regards,

jL
