Hello All.....
I'm trying to re-create a circuit I recently built using an AMV to clock a 4017, with Thyristors to latch 10 LED's through each cycle, ending up with a "light bar" of sorts. Here's a short video of the exact effect I'm after.....

This circuit will eventually be used for model kit lighting, and although I was able to fit the 52 components onto a 1.6" x 2.4" board, it's still a bit too big to fit inside my model. Someone suggested I could do the same job at 8 LED's using a 74HC164, so I bought some of those but haven't been able to match my previous output.
I'm using a 6V supply. I started out with the same AMV as the previous circuit, but thought I'd try using a 3909 for a clock to get the size down even smaller. This just left me with an LED blinking, then 2, then 3, etc..... a cool effect actually, but not what I'm after.
With the AMV clock however (or the 3909), I'm seeing only 7 of the 8 LED's light and latch (seems like the first two don't really turn off fully), and after a random number of cycles it locks up and all 7 LED's remain lit. (or blinking).
I have zero formal training in electronics, and needed some help to complete the previous circuit. If anyone is interested in reading through that process and how I got to this point you can check out the following.....
