737-200 overhead build

Yes, i have used Allied, good to deal with.

Also most of the major electronic suppliers like Digikey, Mouser etc are good for these.

One place i strongly suggest you avoid is Bulbtown.

I tried to order from them 3 times and each one was a complete disaster.

Thanks for your hints

Hi Stijn,

I'm in the same boat like you ... I need bulbs for my B747-400 panels. I found another source:

More or less same pricing!

Does anybody has experience with this shop?

Cheers

I ended up ordering them there. I'll let you know how they are.
They also have the bulbs for the korry's. needed them too.

Excellent.

I think I will order from Diki-Key .. they are in Europe as well.
Need to check the number of bulbs ... I'll keep you up to date about Digi-Key too!

Cheers

I use a uln2803a driver. That is what i use for my korrys. Paralell the pins and you can drive 2amps through one chip.

Use analog output on teensy.

Got that working now, however, the Korry's in these OEM panels are wired up with a common ground and this chip is assuming common +, not a problem with type 2 Korry's, but in type 1 Korry's the internal diode is preventing the light from coming on.

Am I missing something here?
