Hello All,

I am building a +/-15 volt power supply, using a dual sec transformer, full
bridge, filter caps and LM7x15 regulators.
I thought of configuring it as 2 independent supplies,using a 7815 on each
secondary, then tying them in series to get my +/- 15.
(for op-amp use)
Is there any advantage the above config  as opposed to tying the secondaries
to make a center tap and using a 7815 and a 7915?

Regards,

Robert Francisco
