These are really news for me. I still have not bought the supply board.
Am I wrong when I think that T4 accepts two DC types : asymmetrical (0/+) like from your Meanwell or symmetrical (+/0/-) like the offered power supply board ?
I wished I could comment it.
See posting before from Nick. It looks like that your modifying is obviously not needed. On the other hand: if Nick is wrong you are in the game again
Why abuse the center-tap like that?
Attached are different schematics.
Edit: also make sure that you take a transformer like +-17.5v, not +-35v.

Basically the same thing I created...
No, 17.5 will not accomplish his goal. 35-0-35 toroidal with both secondaries tied together to achieve more amps.
At least that is what my approach is, BUT since you have not bought the board, don't do any of this

Yes the board doesn't add much to it. there is already a rectifier on the T4, so if you want more capacitance, you could add more to the T4 board.
Indeed, the rectifier is not a bad one. My main issue is the soldering and integration of several caps (up to 20 pieces) into a chassis. It's senseless to design and build only one or two extra pcbs for it.
BTW: I would suggest to show before and after schematics for electronic dummies like us. It makes also comparing easier for everybody.
Before (for symmetrical DC out):
After - Whaleman's suggestion - (for asymmetrical DC out):
Thanks for your attention

Just another good and easy solution...
Hifimediy T4 TK2050 con Cap KENDEIL di filtro
Sorry but it's in italian...Try Google Transl, then, if needed I can help with translation.

Sonic Performence and sound quality
Hi all together,
i'am new here.
The reason to come over here is, the interest on different t-Amp's and there sonic performence.
So please can somebody tell me something about the T4 performance as well against other T-amps like Arjen Helder's MKIII TA2020 and MKII STA508 Tripath Mono.
Many thanks in front for your answers. " i hope many "

It's just easy to explain: "T4 has the balls ..." especially with 6 - 8 Ohm speakers
Wowwww !! Thanks and mille gracia ... The pics are nearly telling the whole documentation. Kendeil, an italian cap brand which NAIM also would use in some of their amps.
I am really curious about a sound difference between 2 big Keindeils and 15 smaller Panasonics. These are good news. If there are to be cleared questions I will ask you
I've translated a piece of the post I've linked,
"[...]Con i kendeil l'amplificatore ha acquistato punch e presenza, ma soprattutto tenuta ed equilibrio; inoltre mi sta dando molta soddisfazione nella dinamica, dove la scheda eccelle già di suo liscia, ma con i nuovi capi è il top rispetto a tutto quello che ho sentito in classe t.
il suono è molto naturale, la scheda non dà accenni di fatica neanche a volumi elevati, l'ascolto è assolutamente rilassante e poco caratterizzato. sono soddisfatto e impressionato, perchè oltre a mostrare correttezza timbrica la scheda è molto musicale, ma anche analatica.
assolutamente consigliata, un plauso va ancora una volta a Yulian [...]"
"[...]With Kendeil caps the amp has gain punch and presence, but most of all control and balance; moreover dynamics it's very satisfying, where the board it's already excellent by itself, but with the new caps it's the top in comparison with all what I've heard in class-T.
Sound it's very natural, the board doesn't seem to be exhausted even if playing at loud volume, listening is absolutely relaxing and little "featured"[read coloured]. I'm satisfied and impressed because, beyond showing timbre accuracy and being very musical, it's still very analytical.
Absolutly reccomended; thanks once again Yulian[...]"

that's why I am also impressed with the well made Tripaths. I hope these Kendeil are not too expensive at all ... thanks again Centvrion.
