I’m restoring an FT-101ZD MK0 which has an open-circuit S-meter lamp. ?Are these 12 volt lamp assemblies with leads still being manufactured? ?What is everyone replacing these bulbs with?

Thank you.

-- interesting that you should ask about the bulb for the s meter as I was going to ask the same thing today.? found out yesterday that my light is burnt out for the S meter as well.

That bulb assembly is really hard to find.?

Most people replace it with a frosted lens white LED and a series resistor to limit the current to the LED at about 10ma-15ma.?

Thanks Bruce.

I will continue to see if any of the collectors I know might have one in a junk box somewhere.

I have landed my hands on a new set of 6164 tubes which are believed to probably fit the FT-101.? I will find that section in the service manual to find out if these are compatable.? At the same time, I will try to find documentation about the correct bulbs and the S meter light.

Thanks again for the input Bruce.

Best to use two 6146B tubes in the FT-101Z series.?

Bruce:

I will assume the 6146B are not equivalent to the 6156?
