Hopefully not as complex as MC's problem, but I have a Bell & Howell electric drive viewer/editor model 209 - a super little machine for both Standard and Super 8. It has different sized apertures and sprockets for the different film types, so does not ruin either.

The bulb, though still intact, is quite a rare looking object, so I thought I'd post this note to see if anyone has experience of sourcing a replacement bulb.

It is 6 volt, 10 watt, small bayonet cap type, with single contact and with a straight filament. The glass envelope is pear shaped, not round, and is pre-mounted (soldered) into a flat oval metal flange, which is held by two screws into the body of the editor.

B&H call it a pre-focus assembly, such that no lamp positioning or adjustment to achieve maximum illumination is required once fitted.

The B&H part number is: 42496

I can't seem to find one anywhere. The only solution as far as I can see so far would be to make one up each time a replacement is necessary. Not impossible, but a bit fiddly.

Any ideas?

GOSH! IS THAT THE TIME? MUST DASH! CATCH UP WITH YOU ALL LATER.

Best,

Dave.

Hello Dave
This should be what you are after:

http://www.7dayshop.com/catalog/product_info.php?manufacturers_id=&products_id=9137

They have Hama splicing cement and Kodak K40 Super 8 at the best UK prices as well - hope this helps, back to the gardening for me now making the most of some lovely weather here in Kent today.

EDIT: I've just re-read your post Dave and realised your editor uses a similar bulb to this but mounted / soldered into a mount - I reckon it would be worth trying one of these in the mount as the shape of the glass envelope may not be as important as the actual position of the filament in relation to the film. This is the only editor bulb I am aware of that is easily available, hopefully someone can ID yours - can you post a photo for us to see it?

6 V 10 W editor lamps are the same as 6 V motor cycle rear lamps. Mine cost about 70p from my local motorbike shop.

Nice one Tim - never having been into motor bikes I've always written off auto bulbs as being of no use as those on the cars I've owned all use 12v or higher, never 6v - I'll have to nip into the local motorcycle shop to investigate.
I have previously bought editors that were sold cheaply, described as 'having a very dull image' to find the only problem was the seller had fitted a 12v 10w bulb instead of the correctly rated 6v 10w bulb.

!!!!

I have exactly the same problem with my Elmo 912 editor... it just seems so dark, not like what it should be. Never thought it could be due to an incorrect bulb. I'm going to have to check into that. [Cool]

Yes I agree with Tim. Tey are the same as the old 6V rear motorcycle bulbs. If you cant find one then I know that Phil at Calssic Home Cinema sells them. He also sells an adaptor which allows you to convert them the QI lamps.

Jan, they are a small 6V 10W Tungstan Halogent lamp designed for editors. They are quite small and have 2 pins like most halogen lamps. You can buy a converster which is simply a lamp baynet with 2 pin holes to plug the new QI lamp straight into it.
CHC were certainly selling these. I'll have a look this eveing to see if I can take a pic of mine.

OK, and what's the advantage of QI bulbs over regular ones (I'm feeling mighty clueless right now, so bear with me) [Smile]

Hi Kevin et al,

Just returned from my business trip so am a bit jaded this evening. I'll take a pic of my editor bulb and hopefully post it tomorrow. In this particular case, the shape of the glass globe does have a bearing, as the filament sits quite high up in the glass envelope. The standard bulb you guys are all referring to will not work without major re-fitting, as the filament is too close to the base of the lamp. The whole of the lamp is too short. One final point - the filament MUST be straight in order to focus properly - like a projector bulb filament - I don't believe this is the case with motor vehicle lamps of the type described. The filament is usually curved and not precision positioned. The one shown in the 7 day shop website is correct from that point of view, but not suitable for my editor, without, as I say, extensive modification.

Looks like the Quartz Iodine Mr Elmo is talking about might be the way forward! A much brighter whiter lamp for the same watts!

Best,

Dave.

"Much brighter," well OK, I kind of guessed that one. [Wink]

SO! Here is the lamp assembly. Its overall length is 40mm, and distance of the filament from the base contact is 35mm.

Thus it can be seen that a standard automotive bulb is totally inappropriate, though I appreciate the sentiment, but have already considered this initially, till I discovered it was a non-starter without making up a completely new mounting assembly.

Kevin, (Mr Elmo), any thoughts as to whether your Quartz Iodine lamp and adaptor might work? A more intense and brighter light would be to great advantage if the combination could be modified (where necessary) to achieve the desired end result in terms of final filament position.

Cheers,

Dave.
