Are these bulbs available?

[Curti]

I Googled around for a while , but was unsuccessful.

The little screw in 6V bulb is used in Radio dial heads.

I could a few of them.

These should be available on-line from larger distributors like Mouser Electronics:

Mouser Electronics - Electronic Component Distributor

Their catalog shows a couple of 6.3 Volt bulbs (CM40 or CM46):

Mouser part numbers 560-1775 or 560-7320

Also Chicago Miniature Lamp lists some threaded base 6.0 and 6.3 Volt bulbs:

Mouser is a distributor for Chicago Miniature

Excellent, that is what I love about this forum. Thank you Friartuck!

Curt,

Radio Shack via the on-line store has two more candidates;

part number 272-1142 a 6Volt bulb

or

part number 272-1128 a 6.3 Volt bulb (this one seems to be the standard #40 that was mentioned above from Chicago Miniature)

RadioShack - mobile phones, MP3 players, laptops, and more

Might help if you had a ruler in the photo as there are a couple of miniature screw base sizes. I'm guessing that you have a T-3 1/4 bulb with a miniature screw base.

The two candidates I see for that in my 1970 GE Mazda miniature lamp guide are:

#40 (Radio Indicator) 6.3v, 0.15 amps, 0.52 CP

#46 (Radio Indicator) 6.3v, 0.25 amps, 0.90 CP

Were it me, I'd be looking for the #46 as it has the higher candlepower rating.

If you search for #46 lamp on Radio Shack's web site it turns up a bulb that looks right: 6.3V/250mA Incandescent Flashlight Bulb (2-Pack) : Flashlight Bulbs | RadioShack.com

If none of the above turn out, and they're considered obsolete, you might try donsbulbs.com.

I know nothing about them or their prices, just seen them mentioned in other posts. Good luck.

McMaster-Carr has the #46 bulb. $5.63 for a package of 10. They also have the #40.

Thanks for all of the responses. #46 is the bulb needed I was able to order a some.
