OK, so if I follow the recommendations, I should just build the SissySIT with the boards I have now. No sound advantage to waiting for R3. I have the THS-51S that I bought for the SissySIT.
I also have 6 of the K182ES and 2 of the K180 SIT as well as 2 pairs of K60/J18, so I'll be seeking recommendations for where to use these. I should probably set aside a pair for the impending VFET after the hubbub of the lottery dies down. I currently have an M2X and Sony VFET (old store boards but not the anniversary model and using K60/J18 instead of the correct VFETs). Should I build the M25 also? (I would need more boards but I assume that's easy).
Soon I'll also need a bigger house or storage unit...

first thing is having them (Tokins) sorted by Ugs (if not having curve tracer)
best would be to have them tested in both ways, so you can sort them (for) , and match (between) them
that should ease which ones to use for anything you decide
with that (decision), Mighty Moi is not helpful ........ mine is to make them, not to choose them
translated (Babelfished?) - mine is to elevate level of confusion and indecision

Oh yes, both wonderful!
If your speakers have a wild impedance swing this will change the gain of the singing bush tailoring the response to the speakers. For better or worse. You can add a zobel or just a resistor to flatten the response.
The SissySIT is amazing! It’s a fabulous DEF push pull output stage. DC coupled on the output. I happen to like driving it with a separate driver stage, there will be many front ends coming to dive the new DIY Vfet amp, so lots to play with.
Thanks ZM 🙂

Now a SissySIT with front ends that can be changed out would be cool. Like the M2X or new VFET.
it would be SissySIT P
I believe present iteration with autoformer gain stage and future iteration with active FE ( with NFB and all bells and whistles, including Bal input) is ticking all the boxes
at least I'm not interested in making it even more versatile ( how many times I wrote that I'm not interested ...... )

No I get it. You need to change the entire board 😂. I like it.
Zen looking at Nelson's new Sony sit amp it looks like he is using a 220pf and 10K resistor across the secondary of the input transformer but you are using 680pf. Why did you need the larger value ? And instead of using multiple pairs of jfets I wonder if a high current buffer could be made from just a pair of Ld1014d each with something like 15 ohm source resistors to set the bias or would it be to noisy?
beat me, I'm too confused now with all different files floating in my head, so I can't be sure of these little details
also , fact of me just starting with morning coffee tells you all
in short - 10K-680p is compensatioon strictly for Edcor 600:15K, taken directly from Pa's M2; other autoformers doesn't need that
Revisions:
R.3 is strictly for classic repeaters ( 600:600)
quote of note from upcoming schematic:
in R.2 I made a mess ( same reason - working on too much things in same time) and remedy shown in post #1886 Babelfish M25, SissySIT - general building tips and tricks, so that option applicable to Edcor 600:15K without change, and with change upper quote stays
origin SissySIT (without R in name) , as written in post #1 of Babelfish M25, SissySIT - general building tips and tricks :
conclusion:
- if you're not sure which xformer to order and you're confused ( easy to be when dealing with Mighty ZM), just ask
-if you have them already , even if there is some obstacle/compatibility issue, just ask and we'll solve it with tiny 'xacto knife action and inch of tiny wire

Very cool.
I’ve had a pair of Cinemags waiting for this one since early last year. It sounds like R.3 is going to be worth the wait.

I've scanned lots and lots of pages but so far I've been unable to find a picture of a sissy sit build showing pcb and external semiconductors fixed to Modushop heatsinks
I can never get the direct links to work properly but look at posts 746, 759 and 761. I stopped looking after that but all 3 of those (different builds) are on Modushop store cases with the Tokin elevator thingies mounted.
Found another one with good lighting and clear angles - post #797
