Hello,
currently I am working on a FERNSEH A.G. prewar tv set, the DE 6. The original picture tube has broken filaments. Here are some photos:

No printed schematics are available.
One engineer in the past made some hand-drawn schematics, but did not completed it. Meanwhile I have got the power unit working and the video amplifying and demodulator section. The last photo shows the spare picture tube for replacement.
Kind regards,
Eckhard
