Just went through this thread again. There seem to be different "versions" of the FirstWatt active filters. B4 and B5 are described on the FirstWatt website, and some others that I don't understand.
Which "version" will be available in kit form in the diyAudio store? When? I wouldn't mind a B4 right now 😀

So we expect both versions to be available eventually. The answer to the 'when' part of the question is somewhat vague: soon
Patience is the word around here. Again, all the good for those who wait.
Future kit for match Papa amplifiers with the drivers !Thanks for the news Mr Pass
and congratulationsAttachments
I routinely make them this way for people to play with. Saves me money
on give-aways. Product which just has holes in the boards for wire is
standard issue for the store, so you can use what you like.
To be precise, of course I asked it because of my balanced-mania.
So may I use two boards in balanced, for stereo?
I think, I must upgrade my Behringer CX2310 to something better, B4 or B5 or something.

That is the easy way. By the time I have have converted balanced to
single-ended and back again, it costs as much as two boards. The
boards would work fine with 6 RCA and 3 XLR.
Actually, I don't need to convert unbalanced to balanced and vice versa.
I want it to fully balanced, along the full path.
If counting my unbalanced sources there are quite few, perhaps a Revox B261, Revox A77 and an AKAI GX630D can be.
Quite rarely using them.
The jfet in the middle of the pic is soldered in backwards according to the screening on the pcb 🤔
An NP designed crossover will be perfect for this system.
The ribbon tweeter I have posted recently will be driven by the F4 Beast with unlimited current.
The 4 x midranges will be driven by a simple F7 variant.
A separate subwoof will be driven by an Adcom GFA555.
All in all, a 100% NP active signal chain.
I will want a stereo 3-way with crossover points of 100Hz an 3 kHz. If this requires 2 2-way crossovers, that would be just as sweet as a single-box 3-way.
I am stoked that an NP designed crossover will be available in the DIY audio store.
