I have one of those OPA541 signal generator amps. It works as advertised powering with my two channel Leader LPS-152. However this limits me to about 22v output with the Leader’s +/- 25v max supply and I need 30-40 output.
I also have a B&K 1743, a single channel 35v unit. I can get up to 50v by combining the Leader’s two channels, and with the B&K I could theoretically get + and - 35v which would get me my 30v output from the amp.
But the input to the amp has just three lines +, - and ground. I would have thought I could connect one PS to the + and ground, and with reversed leads the other to - and ground but that does not work. Is there a way to accomplish this with effectively two single channel power supplies?
Thanks,
Jeff
