Pa's Next VFET?

[dantwomey]

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?

Beautiful.

 

[Zen Mod]

Ok, either be less Greedy or, that being impossible, be more Greedy in more Silent Way

like a Pig in da Mud, I'm wallowing in my Greedinessssssssss

Greedy is one thing. Impatience is another, especially for something that's free.

I'm reminded of my daughter's dog constantly whining when food is nearby, or the word "walk" is inadvertently mentioned.

whatever it is, ZM is Master of Wallowing

Winter will arrive here soon so we need something to entertain ourselves!

Could be worse - they could be greedy for someone else's amp.

metal has arrived, final pc artwork tested and on order.

 

[WBS]

Waiting, (somewhat) patiently. 🙂

... 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.

At least Pa has some patience. 😉

 

[MEPER]

How many VFETs pr. channel?

 

[Soundhappy]

One Vfet for not push-pull mono output stage.
What is another non Vfet transistors ?? 😉

 

[MEPER]

The VFET is TO-3 housing as far as I remember?

 

[Ben Mah]

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

 

[Soundhappy]

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..

 

[MEPER]

Ok.....I guess the kits will be sold out fast if the VFETs are included in the kit.....

 

[Soundhappy]

Two Vfets is included in the kit = one stereo amplifier.
All be sold out very quick..
I have Vfet's but probably need the other mystery TO-3 (mosfet?) transistors , pcb's and audio signal iron..
Stay in tune anyway 🙂 Good luck
