winslow said:Peter Daniel had some (or I think he did)...but the real question is if you wanted to build one, where would you find the power jfets?
Magura said:The ZV9 is not really pcb layout critical, so the real easy, simple and cheap solution, is to get a vero board or do it point to point.
Solution number two if the vero board scares you, would be to build it on a ZV1 board, which is readily available, and just cascode a JFET in on that. The CCS differs from the Aleph CCS originally used in the ZV9, but to my ears and many others, the CCS of the ZV1 sounds better.
I've read your brief comments before regarding the CCS and the Aleph CCS . According to the ZV9 article the reduction in distortion with the Aleph CCS is dramatic. Perhaps you could be more specific on the subjective side . When the time comes to test , I'll try both and see for myself.

Peter Daniel and Veteran posted a single sided board layout in a ZV9 thread somewhere. You can fairly easy etch a pair of boards for yourself, as I did. You can leave out the Aleph CCS connection, if you wanted to.
Persistence found me a set of Veteran's boards ..They are on there way .
When I bought the LU1040's ,I did so based on factors which included your comments on the ZV9 . Did you also leave out the Aleph CCS ?? With only three components involved , trial in both directions is a simple matter .When I get there that's what I'll do.
Meantime... Babozen here I come!!
By the way, this amplifier will only see above 200hz . with 93db speakers.
