Has anybody seen a currently available PS board for dual secondary transformer? Or even just a board for the rectifiers (TO 220) There have been some around, but I don't see any available right now. Sure would be nice to see something with thick traces and hefty plated holes. Heat sinking 4 devices/rail is a PITA

.

This is the issue.
For those of us who think our discrete devices have some impact on overall sound.

Guys what voltmeter accuracy would you consider adequate for adjusting the bias/offset?
Would a 10mV error be acceptable (Keeping the max acceptable offset reading at 40mV to compensate)

Set bias at whatever your sinks let you go away with it no mather is bit over.

Ofset is main thing 0 is magic number.
Apcettable is as low as you can get it. get it?
Meter wont show much error arond that yes?

what voltagge does it read when you shorth leads?
