True test of one's wiring skills is in the first power up, be damned your detractors and critics. fire it up and see if it smokes, if not then your wiring is good.

No use showing us the picture of the wiring layout as it does mimic your circuit diagram. Try working on bigger value (and voltage rating) by pass caps though. It looks pretty puny from this view, try working from that end that is where most hum issues start.

JM

PS

Now I am shy to show a pic of my just completed, VT52/VT52 with hum cancelling rectifier monoblocs. I have to check again, I got almost .3 mV on a shorted input hum test. It should be 1st test you do, or else all bets are off.
