Default Re: Dux/Philips Swedish TV-Radiogram!

Wow! What a thoroughly well designed TV set.
A frame grid valve in the tuner (PCC88) and four stages of IF amplification means this set was without doubt intented for use in difficult reception areas. A noise gated sync separator using the ECH83 triode-heptode and flywheel sync takes care of any line timebase sync misfiring.
Unusual to see the two PL84 valves in the transformerless push-pull sound output stage.
The circuit around B19 (ECC81) the on screen tuning indicator needed some further study. Thanks to Tricomp it is explained. BildLots (imagepilot?) It is a truly remarkable feature. All this in 1959!

DFWB.
