A good option for dual-transformer configuration:

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

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

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

I will add them to my kit please

manniraj 16th August 2019 06:50 PM

Yes please add them to my kit as well.

thanks

cl00sed 16th August 2019 06:59 PM

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