Romy, I'll be digging round in my amps tomorrow and intend to install a filter for the red tweeter while there.  What should I be aiming for?  7kHz first order from memory, but hoping you can confirm.  Such a filter could be achieved just by changing the coupling cap (eg. 0.00022uF for 7.2kHz), but I won't get that drastic just yet.

Great to hear that your sound continues to improve. 
 
I probably will be doing this weekend the same experiment. It is hard to say what crossover point to use. The default crossover has somewhere sub 2K and I used the max gain for the tweeter, where the sound floes over the cap Not good and there is a lot of expected improvements in there. I do not know the Red tweeter impedance but if to presume it is 8R then I will start with 7kHz Bessel curve, it will be 1.63uf cap and 0.31mH coil to ground. I will not go for anything electric as it is works I would like to build the filter at the basis of the Milq’s driver tube
