F-5T V2 and planars R3

Thanks Dirk,
I think I'll implement a stereo-to-mono converter just for the sub on the same box as the 6-24 cross, then I'm going to remove all the potentiometers in the signal path, I've removed them all in my hi-fi chain, only the preamp has a stepped potentiometer made from resistors for volume, so fixed resistors in the 6-24 cross as well.
Thanks for your advice and experiences .
The separate power supply is also regulated?
Greetings Giubos
