Sorry Carl, I guess that would help, wouldn't it!
It's a Model 409

John, here's your schematic: http://www.nostalgiaair.org/PagesByModel/662/M0007662.pdf

Add up all the series filament voltage ratings = 108V. Nominal line voltage = 120V. 120-108 = 12V. Try any lamp voltage rated near that.

Whoa, Doug, I gotta disagree. Doesn't R32 33w, 2W WW take up the slack in the filament Voltage for the solid state rectifier? Looks like to me that the bulb is across 120 V. period. The parts list calls for a bulb assembly, so I'm thinking neon, perhaps a NE-2 and a resistor (100K ?) in a clip-on assembly. If so, John might disassemble the thing and buy a NE-2 at his local Radio Shirk, I mean Shack, and be in business for about a buck, and have an extra NE-2 for the next time. N'est ce pas, mon ami?

If it is the device noted as PL or P1 ...looks like a 120v lamp...no?

Thanks guys,
I tried a 12 Volt filament bulb about the size of an older style christmas tree light bulb with the two tips on either side that twists into place. When I pluged it in, it lit up rather nicely for a split second then died! I am going to try "Radio shirk" and try the 120 volt bulb.
Thanks again everyone.

John,
I pulled the bulb out of my 409 and its marked 10w, 115-125V. It is a double contact bulb similar to an automotive lamp with a pin on each side.

Hi

What does the socket look like? This could be a lamp like used in night lights? The schmetic shows it with a filament not neon. Need a 120 volt lamp for sure not lower voltage.

Similarly ...I'm now working on an Arvin 664A that uses a 7 watt 120volt screw base lamp. Similar to a night light or an older Christmas tree lamp.

Looking at the picture in Resources, the thing isn't nearly big enough for a 7.5W 120V. bulb. Something like that would be great, for he could save himself a trip the the hated Radio Shirk, I mean Shack.

Shame on you Doug... are you trying to be perfect again..?

Like the guy who said:
"I may not always be right ...but I'm never wrong.
The only time I was wrong was when I thought I was wrong but I ended up being right.. so I was only wrong thinking I was wrong."

lol... :-))

:Well guys, I finally found a 120 volt, 15 watt bulb at Menards of all places that works fine, a little high in the wattage department and quite bright! It's the same type of bulb that will work in a vacuum cleaner, according to the label.

Thanks again,

John.

What kind of base does the bulb have? Please describe. You really should have a much lower wattage bulb in that socket. If you describe the base, I can find you a proper bulb (such as a nightlight bulb, or something with a similar wattage....idealy 5 to 7 watts).

Thomas,

The base is the push in and turn type. The bulb has one tip on either side.
I would be interested in a 5-7 watt bulb if you have one.

If you want to sneak a 1N400x diode in series with the bulb, it will be A) a dimmer bulb, B) a bulb that lasts about forever, and C) easy to restore to original.

Yes I agree with "linsonl".. that's the answer!
The diode is a perfect and simple solution.

By way of example...I've had a 1n4004 diode connected in series with my regular 120vac/100watt light bulb in my front porch lamp that has been burning 24/7 now for well over 15 years already!!

Hi Peter and others:

My name is Lewis Linson, bellsouth assigned me the linsonl for my e-mail address. I try to click on Lewis L., but sometimes hit the e-mail instead, so you get the e-mail address instead. I got the idea from a fellow I worked with in an avionics shop at Delta, he had a soldering iron holder hooked to a microswitch, and when he inserted the iron in the holder, it opened the switch and inserted a diode in the circuit, making for a cooler iron and when he picked up the iron, the diode was shorted, and in about ten seconds the iron was ready to use, with a clean tip. I used the idea, like Peter did, in my post light, using a doide I fished out of the trash from a DC-8, which was sealed in epoxy, with axial leads coming out of it like a capacitor, only stranded. The lamp has been running every night for years, and looks the same from the street. I did the same with a night light in the bathroom, it was too bright and burning out all the time, there was just enough room across the on-off switch to install a diode, now it is a dim-bright switch, with no more lamp changing.

Kind of a funny thing, we had tube-type radios on the 28VDC, piston planes and had inverters to make 115V, 400Hz, to run the radios. We have 115 V., 400 Hz. on the jets, and have Transformer-Rectifiers to make 28 VDC to run the transistor radios (and a lot of other stuff, radio, instrument, computer and and other, that runs on DC as well, they may have 2-3 hundred Amps of DC, or more)
Lewis

Here's a 7 watt 120 volt double contact bulb. Look down the list a ways. http://1000bulbs.com/products.php?cat=C7-Commercial-Lamps

The diode trick will make your 15 watt bulb glow dimmer, though, and will make it last a long time. Take your pick.
