thank you guys for help...
i populated another board and that one worked fine...and the amp is complete.
However i intend to troubleshoot this faulty board some time later..

here is the pic of current set up (though temporary)..


Once again , thank you guys..

Hmm having the transformer primary just sticking into the socket like that seems pretty unsafe.

Any particular reason you used a R core transformer instead of a more common toroid?

The socket actually snaps in after the cables are inserted so it was pretty secure.
In any case,it was only for testing that one time. I have already connected a plug now.

The R-core transformer comes from the most reputed manufacturer here locally.They have stopped making toroidal transformer now, citing better performance from the R-core design.
I do think that the R-core trafos provide a blacker background but it could be just placebo.

Good idea! Congratulations on the working setup.

Thanks agdr! You have been a great help.
With my limited listening in past couple of days, I can safely say that the B22 is a definite step up from my previous EHHA rev.A amplifier.
Definite worth all the blood & sweat ! Thanks amb!
