Hi Valery - another noob question. In a post (#8) under the VHex+ thread, discussing the Simplestark, you said the following: "IPS requires one pair of 2sk246/j103 jFETs, relatively rare, but still available these days."
Does this apply to the Simplestark, ie - do I need source these rare jfets to build the Simplestark?

Thanks,
Jerry

 

[jwilhelm]

We have some of those jfets in stock.

Hi Jerry,

Yes, you will need 2 pairs of those jFETs.
BTW, you can download the exact schematic of the amp if you create an account (free) in the store.
As Jeff just mentioned - we've got some stock so we can help those of you who have a problem obtaining them.

Cheers,
Valery

Great. And the cost?

 

[jwilhelm]

Great. And the cost?

We can add them to the kits for $5 for a complimentary pair.

 

[pinnocchio]

I will add them to my kit please

 

[manniraj]

Yes please add them to my kit as well.

thanks

 

[cl00sed]

Include in my kit too, except those rest all transistors are available

 

[yogiDIYbear]

Please add JFETs to my kit as well. Thanks.

 

[jwilhelm]

I've never had time to even build prototypes for this amp yet myself so this is a good excuse to build one and test some other concepts we've been working on. I've started designing a chassis for it. If there's any interest in custom pre-drilled chassis let me know and I can run some extra pieces while I have the machines set up. Finished price will likely be around $350 with whatever you would like for engraving or laser work. I'll post some more screen shots when I get farther along with the design.

 

[thimios]

Ah, the final step that i never complete.

 

[jwilhelm]

That's the problem I always have so I'm building the chassis first and the boards last this time.

[tuyen]

Please add Jfet to my kit too please.

With thanks

 

[outtek]

Hi, also add the FETs to my kit also in this case please, but make it double the quantity just in case . Thanks.

 

[twocents]

Ok, if I am correct, this is where we stand currently:

tuyen - 1x (1) + jfets
pinnocchio - 1x (1) + jfets
yogiDIYbear - 1x (1) + jfets
manniraj - 1x (1) + jfets
outtek - 1x (3) + 2 x jfets
cl00sed – 2x (1) + 2 x jfets
PurpleTube – 1x (3)
Touchdown - 1x (1)
twocents – 1x (2) + jfets

 

[touchdown]

Jfets for me too, tnx!

tuyen - 1x (1) + jfets
pinnocchio - 1x (1) + jfets
yogiDIYbear - 1x (1) + jfets
manniraj - 1x (1) + jfets
outtek - 1x (3) + 2 x jfets
cl00sed – 2x (1) + 2 x jfets
PurpleTube – 1x (3)
Touchdown - 1x (1) + jfets
twocents – 1x (2) + jfets
