Idefixes, if you have thermal tracks than first make point to point wire nest. Mount TT-s on a heatsink, than step by step add and wire parts, similar like sonnya did. I think it is not very demanding job to do and test, before you go to PCB. You will also check if everything is OK and if the sound is acceptable.

And don't forget to thermally couple input pair.

I am not aware with point to point.....and find funny pcb art work as i can produce at home... I have 5 couple of NJL1302DG/NJL3281DG on hand , 47.000µ 35V and a 400va 2x18V toroid transformer i can swap just for test from a another project

It is an ideal opportunity to try with P2P, sch is simple, diodes are integrated, so really low parts count. You will also learn how good P2P is, it will hardly be beaten with any PCB.

arf no BC560/550 but 2sa970/2sc2240...

They are fine, if you can measure hFE, it should be max. let's say 500+
Pinout is different to BC's. It will be very nice to see another wire nest, just go for it and please don't forget to take pics.

I not shure to try P2P, bad experience with tube electronics....
A couple of houre with eagle see attachement ... 123x69mm

New tryout on pcb layout, i swap big caps out of board so the pcb mesure 100x56mm

Hi Idefixes

Very nice little neat PCB.

Now you put us all in a expectation ...

Good lord that looks intimidating. It would take me a month just to do the pcb. Might try anyway after the simple tssa.
