So, I got to hear a SIT-4, which is a Tokin amp in common source mode (i.e., it has voltage gain too). Absolutely glorious sound. I want to hear it in the TDV chassis. It should be relatively easy: just put the choke on the drain pin and apply a little feedback.
Ben has reported that he prefers his followers to CD mode VFET amps. For sure, the follower will have less distortion, but the SIT-4 has such a glorious sound that it will be worth the experiment.

I asked Slagle if he would make something for these amplifiers when Ben Mah's posts were made. He said yes and then I never heard back. I did ask him an additional few times with no response. I had bought more than a few pieces from him so he should have known I was serious. Who knows?
I am using the Lundahl filament choke - and having nothing better to compare it with or being able to take measurements, I am able to be blissfully pleased and ignorant of misbehavior that I cannot hear.
It would be fun to hear what they could make with their larger cores. Maybe they would consider an order if there was enough interest for a small run. Who knows what small would have to be?
Maybe Slagle would consider making a small run? I would want them.

Here is a photo of the stack we listened to. Bottom 2 are Tokin SIT prototypes, middle is SIT4 proto,So, I got to hear a SIT-4, which is a Tokin amp in common source mode (i.e., it has voltage gain too). Absolutely glorious sound.
above that is small version of Beast w/ 1K Jfets, top is ACAmini.

and where are my Tannoys?
without them as reference, no good future amps ........
don't know anything about these .......

My progress so far and I went with suggestions from ra7, CodyT and Eric looking at my parts bin what I could find to meet the schematic. Used 22R, 6.8k and then 2.2R *2 for R3. Will solder a 220/3w resistor across the spk+/- as per the original schematic instead of 470/3w suggested as I have these resistors with me.
Will be using 2 of the 4.7uf film caps and then a 18v zener diode. I am going to repurpose the 193T from the LU amp as well as the 24v 5A smps along with the Tuba filter
