The amplifier has been completed and it works extremely well.. Changes from the original schematic includes Individual bias pot provided for all tubes ( to get equal current draw). The coupling cap was changed to 400 v ,0.43 MFD, metalised polypropylene..
That's great! Pleased you like it.
You search differences to which schematic? Boards already have individual bias pots.

I did the Yvesm original schematic with Pcl86, no PCB,But point to point.. Individual bias pots and the current draw resistor in the Cathode are the differences from the original schema, and not to forget, Potentiometer is 22k linear.. ( log pot not suitable for my liking)
Omg! 136 pages to go through to get all the details: what OT primary, what PT ht voltage and power, input sensitivity for which power etc
I take it that the schematic numbered “8” in the first post is the final (does any such thing exist on DIY) schematic that can be trusted etc.
Could someone kind and empathetic enough tell me in 2-3 sentences why this schematic is so nice/ works so well, besides its apparent simplicity ?

That configuration triodifies the curves of the output tubes, giving linearity and damping at the expense of the phase splitter load.
Not sure which schematic “8” you are referring to. Attached is the final version of the “official” schematic for the Baby Huey EL84 version that I have. There were a few minor changes - Zintolo, do you still have your list of changes to the EL84?
I did a thread about them (including some preferences of mine): https://www.diyaudio.com/community/threads/slowly-building-three-baby-huey-el84-with-notes.358831/
Jazzman, Thanks! I got these VU meters from theaudiocrafts.com,an online electronic spare shop from India. It is the Nissei TR 35 VU Meter and it is widely available across many online sources
Sarà il caldo ci metto molta pazienza ed ecco un lay6 di BW.

If I look at it like that, I would say at first glance that you should better leave it 😱
Forum language should be English, then the next one starts with Kisuaheli?

Hi

Hi ilorev,
Well, most speak English. Why have everyone else translate?
It will be the heat I'll put a lot of patience and here's a lay6 of BW.
