saba: 630WL; Weltsuper Bargraph

Fellow Radiophiles,

One of the uploaded photos of the front of this Saba radio shows the neon bargraph tuning indicator.

The neon indicator looks like one of the Russian IN-9 or IN-13 analog bargraph tubes because of the mesh anode that seems visible in the photograph. The very sharply defined glow also looks like the glow of one of the Russian tubes.

 

I cropped this small section of the closeup photo of the dial area that was uploaded by Bernhard Beier.

 

Mr Mirko Brandoni in the German language forum, is looking for a replacement for the neon indicator.

Perhaps the suggestion that Mr. Dietrich Grötzer made to use the Russian tube substitutes has already been proven in the uploaded photo.

The IN9 (14cm) is a little shorter than the IN13 (16cm). The IN9 (~9mA) also takes a higher maximum current than the IN13 (~5mA).

Both bulbs strike around 130V-140V and drop 100V-110V during operation.

The IN13 seems to always come in neon-orange, but I have seen the IN9 in neon-orange and in purple.

Regards,

-Joe
