One of the items I've had most trouble with is the the Timer. There seem be be issues with all 3 of the modes.
1/ The Timer: Works somewhat.
Connected to an item, the item will indeed be cycling between the on and off states in the correct interval set by the user. So e.g. a piston platform connected to a timer set to 5 seconds will complete a cycle of going up to a certain point, then return to it's initial state in 5 seconds, and it will keep repeating this process as intended.
The problem with the timer is that, when connected to an activation button, it also seems to take the set interval and apply it to the first activation of the item. So when you activate the button, there will be a 5 second delay before the 5s-interval cycles actually begin. I take it this is not how it's supposed to work.
2/ The monostable multivibrator: Broken
If I'm correct, what this is supposed to do is: upon activation of a switch, the connected item changes to a different state, then returns to the original state after a set amount of time. Tell me if I'm wrong on this. In any case, this mode doesn't do anything.
When placed between an activation button and whatever item (I've tried many) and set to whatever timing, it makes zero difference. Activating the button just activates the item, which never returns to it's original state. Neither does anything else happen. The monostable multivibrator might just as well not be there.
3/ The T flip-flop: Also broken
Can't remember what was wrong with this one off of the top of my head, but it also didn't do what it was supposed to do or didn't work altogether. I'll have to set up another chamber to check again, will get back to you on that.
I don't want to come off as an impatient asshole, but have you perhaps forgotten to send me those instances Felix? I would really appreciate getting my hands on a working set of vacuum tubes as I'm really excited to be able to use them. Again, thanks a lot for your time and your help!
