Yes excatly i give the 230vac for the transformer. And my external AC supply already bundled this wires to the chassis. Even it is 230v on wire., due to a little bit current draw, i think it will not interfere to others.

Just kindly reminding . if u wrap the cap. U must ensure its top side is not a metal case exposed. Otherwise u need to stick the teflon sticker before wrapping. I didnt ground the copper film. I just think it is a shelter purpose to outside and inside emitted radio energy. All tricks if not expensive and less effort, I like to try and the naked ear to final test.

@ Shaan: Nice to see that you're up and about, but do be extra careful about your back. Best, IMHO, is to do a few Surya Namaskars daily once you've recovered.
We're travelling, so nothing much is happening-- except reading...

Sorry shunt regulated supply i dont have a circuit. I just order the kit .
Hi CK,

things are moving slow...I could not find any quality radial resistors for R35-R38 , so I used some dale NS -5 0.249ohms (I hope they are ok) Axial 5w resistors which I already had.
Now , a humbled suggestion , Shaan , if u have the chance, please add a pad connected to each source of the mosfets so for people in similar situations as me could use their axial resistors horizontally mounted on the board.
Thanks

Caddock Resistors MP Series should be a good choice

those are for sure very nice , but kind of expensive. cheapest I could find was around 4$/piece. And I already had those dale resistors...
