A question on scale lamps.

[gary_crutchley]

Hi all.

I have a Ferranti 255 that I am currently working in. The manufacturer's service sheet calls for 6.3V 0.2A scale lamps. I have searched online and cannot find these bulbs, does anyone know a source or an alternative. It looks like the original type are no longer available.

Thanks in advance.

It's an AC radio, with 'E' series valves, so the heaters and filament lamps are in parallel.

Use 6.5V 0.3A bulbs (or thereabouts) - they'll be fine!

Don't use 6V cycle or torch bulbs though. They'll work, but they are designed to have a bright but short life.
