the light in my 100 head went out i've seen post about this topic before but i can't seem to find them i'm just wondering what to get to replace the bulb
The replacement pilot light bulb for the K100 and K200 is a
# 1829 (Grainger #6VF92).
It is 28 volts 70ma
(The #1819 is 28 volts 40ma and will work but is not as bright as #1829)
Do not use a 6.3 volt bulb, it will make the resistor run too hot.
The output of the transformer is 42 volts - a 200 ohm resistor is wired in series with the bulb that reduces the voltage down to 28 volts.

I would think any auto parts store will have them. I live in a small town and it's a local auto parts store and they have them. I would guess the bigger chain auto parts stores would have them as well. Don

I checked with Autozone and O'Reilly's Auto Parts and neither of them had the bulbs, at least not under the GE-1829 name. The people I was talking to on the phone didn't sound like they were qualified to look up something by specifications, but who knows. Even a blind squirrel finds an acorn occasionally. I'll go down there and see if I can get more accomplished face to face.

We have a company in my town that specializes in bulbs and lamps. They didn't have the 1829 in stock, nor was there a slot for them in their inventory. They did have a slot for the 1819, but were out of stock. The guy spent some time and located a 24 volt version, amperage unknown. He said it should work, will burn brighter, but won't last as long. I'm going to pick up three of them. Anyone see any inherent dangers in using a bulb designed for a slightly lower voltage? Not knowing the amperage of the bulb prevents any calculations to predict what might happen.
He gave me a model number on the bulb which is 24MB, but didn't know the manufacturer.

You folks might try calling around to some local radio/tv/repair shops as I would bet they have a dusty half full box of 1829 bulbs sitting around that they would love to sell!
Just kidding. There still may be a few of these around, but try and find one that has been around for at least 15-20 years. The newer ones will not stock these bulbs either.
The same thing may be true with the auto parts stores. Try calling one that's been around for a few years, not one of the new chain stores.

There is still one around where I live, all of 45 minutes north of NYC! But I guess they call them electronics repair shpos now, who knows mabe some older music stores that do repairs may have some!

Wow, I guess I've taken for granted that any auto parts store would have them. Maybe I've been buying really old stock. Maybe the parts guy will have to open his big book and order them. I think the last time I bought some they were .90 each.
I think I go buy what they have left in stock.
