Nelson,

For those of us who already have a stash of JFETís, will we be able to buy just the boards?

Quick answers:

There will be a "B5" version for OB's.

SAL OB works great. The "B5" version is probably best as it allows the EQ
for both drivers.

No reason you can't just buy the boards for the Toshiba/LS versions. The
other Jfet versions will be more onerous for those without populations of the
Jfets for selection, and the price of those will be competitive, there's no point.

A little patience, and all will be made available.

Now it's back to moving my stuff in storage...

Thank you Mr. Pass. You are amazing! I'll make sure I'll make it to the Amp camp this year. Last year, I did not make it to amp cap to listen to your talk and Linkwitz's talk and I still regret ever since now that I'm drawing myself to this OB DIY project.

I'm putting pieces together for my first OB DIY project ever and I start with SAL FR driver Active Xover is the last piece of the puzzle.

While waiting for the DIY B5 kit, I'm ordering miniDSP 2x4HD with UMIK-1 microphone to play around and educate myself about XO freq/phase alignment for each driver. However, I know the sound quality wise of Digital DSP can't compare or come closed to the real analog xover B5. That's why I'm still patiently waiting for the real thing coming up soon.

Thanks again Mr. Pass
Regards,
Tom

I had occasion to listen to the 2x4HD at SL's (he's at the other end of Walk
On Beach) not long ago, and I found it very much better than the original
piece such that it is now competitive with analog.

Not so much if you have to convert your analog signal to digital for vinyl...

Thank you Mr Pass! I'm also working on my first OB project with a pair of Coral Beta 8s and Eminence 15". Patiently waiting for the B5 kit. Meanwhile, the Corals don't sound too bad FR. A bit thin, perhaps... Thanks again, Mr. Pass!
