As ZM would say...the Greedy BoyZ can't wait for the next gift?

Last I saw in July,
As usual ZM is tuned into my subconscious.
Just because he loves it so much, the Edcor 600:15K is the
voltage gain stage for very-soon-to-be-released DIY Sony VFET
amplifier.
Listening done, Curves run, part list printed out.
Machinists are carving heat sink metal as we sit here, and final artwork
is ready to go out the door for quick turn-around.
I tried to make it more complicated and obscure, but it's just not in me.
The first offering will be 200 channels using P chan VFET and then 200
of N channel.
Those out there with VFETs already will be able to get kits without that
part.
Regards,
Dan
be patient, enjoy previous gifts
If we were patient then no one would call us Greedy BoyZ?

... ZM is Master of Wallowing
From Star Trek: Voyager - "Sacred Ground" episode from 1996:
Neelix : It should be me going through all that. I was the one who let Kes get hurt in the first place!
The Doctor : Mr. Neelix, you're wallowing.
Neelix : I'm...
The Doctor : Wallowing in useless remorse. I'll have to ask you to stop; it's bad for the patient.
Could be worse - they could be greedy for someone else's amp.
metal has arrived, final pc artwork tested and on order.
At least Pa has some patience.
Yes, VFET follower and constant current source.
With transformer as voltage gain stage.
Two versions - one with 2SJ28 and one with 2SK82.
Initial units are 2SK28, lucky boy.
Parts arriving daily. Final production boards in couple weeks.
Slightly fewer than 200 channels P, 200 channels N
The VFET is TO-3 housing as far as I remember?
Yes Vfet is TO-3 but some other in the same package is used for total of 4 To-3 pcs per channel.
Well we don't know the very last topology mutations..
