Probably the shortest system test video I’ve made in a long time, but I hope you still enjoy it! 
So it’s not up on the wall, is it like a mini system, or is your other system not up anymore?
It’s a mini system. Lettered system tests (System Test A, B, etc.) are with my mini Farday 401140 system. Numbered system tests are with the Simplex 4004 system on the wall, one of which is coming soon.
Great set-up. Though it would have been a lot better if it was an electromechanical horn. 
Don’t worry, I am going to be using some electromechanical horns in future videos. 
Well then I can hardly wait!
