I have found a supplier for these hard to get bulbs… [ 24 Volt 35mA]
Some of the Rogers radios take a 24 volt 35 mA bulb for the tuning indicator[where it gets dim when on the station and bright when off the station]. They are very hard to get .. I have not found them until now.. The fellows name is Ron Miller and his email address is ,,,,,,,,.
These bulbs are about $0.24 each but the shipping is $20,00… I guess for that price you might want to order a bunch because the shipping is for a 5X5X5 carton so it would not be more for more bulbs.
The phone number is 1 800 692 3051.
