Hello Rolf
Yes you did right. I have only used this amp because I just did. It is only for the first tests. I would like the Speakers with a 25W SE triode amp and passive crossover.Through the long bass horn, however strong run-time differences between woofer and midhorn (about 1m or 3 feet). This, I will probably only through a digital delay can be compensated. Or someone has experience with the calculation of passive Time Alignment Crossovers aka Urei Monitors. Passive when it fails, I will 3 Pass Lab amp's build.

Incredible work. I'm very impressed and a little jealous of your skill.
The pic in post 2 cracked me up.
Reminds me to get to work on my current project.....
Hello A9X,
Thank you for your comment.
The first measurement, not so bad.

I like that less:(
The woofer has a delay to the Mid-Horn of 3,56 mSec .
Mid> High delay 0.9 mSec = 31cm (1 feet). That I could control, it is true. (Sorry the photo is bad).Also, the measure to vote.
