I have considered getting it together to come to one of these shows Andre but tbh if they’re anything like they used to be many years ago you cant really get a fair impression of how things sound; too much activity and systems set up in less than ideal circumstances etc etc.
I just end up getting confuzzeled with the noise

Anyway, from what little I can tell the 66’s look like they may be off to a good start with the basic design. Not too happy with the electrolytics though or the hardwiring. I had those back in the 70’s so they must be on their way out by now.
Still, if they sound okay, that’s what matter eh
