Circuitron?

Call them and find out.

So FWIW, I did send these folks an email at the 'info' email address - after calling their number and getting an automated directory that eventually sent me to voice mail.  I got an email response from Steve Worack - who I think is the founder  and company 'prez' - who said they do have a slightly updated catalog (#302) and that he's working on getting the website up to date...

So it would appear that the lights are on and someone is minding the store.  In their older catalog (#301 dating from ~2013) they offer a lot of built-up circuits - ranging from train detection, block control, crossing flasher/gate to power supplies, sound cards and the aforementioned tortoise switch machines and power supplies.  What I like about this catalog is they have a nicely done section on Applications and the catalog itself is more than just a listing of parts, but they have short descriptions of the boards, etc.  So it will be interesting to see what the update looks like.

For what it’s worth, I’ve used a lot of their products over the years, they have what I think is the tiniest 12 volt grain of wheat bulb with leads I’ve ever seen or used....very nice products....I’m glad to see they are still up and running.........Pat

These are Circuitron grain of wheat bulbs I’ve used to make the modern day N&W J’s headlight ....these bulbs are really nice, very user friendly......Pat
