testing the +20, -20 volt regulatorsa on the White Oak board

From Joe on a previous post;

Connect the negative DMM lead to star point ground in your amp.

Plus 20V measurement
Connect your positive DMM lead to the top side of R73R, just to the right of the TO-220 transistor Q30. It is a 10 ohm, 1/4W resistor. This should measure +19.0 to +21.0V if operating properly in your amp.

Minus 20V measurement
Connect your positive DMM lead to the top side of R80, a large 2W resistor just above the board lower mounting stud. It is a 12K ohm, 2W resistor. This should measure -19.0 to -21.0V if operating properly in your amp.

My 240Ti's are in need of trying one of these out

Missing some wattage eh??

You could send the ti's to me and i'd see if they could handle it!

I'm pretty sure they could take it Bring one down to Vegas. You can go out on the town for the wekend and I'll check out the amp

I was gonna sell them since I got the Alon's but have decided to keep them for now. A WOPL 1000 may be just what they need........

Sarcasm! I have a very dry humor
