        Input: 4 x 10 VAC

        Output voltage: +4 VDC, -4 VDC, +/- 4 VDC with voltage tracking

        Output current: up to 80 mA

        What are the tolerances for input voltages?

        If 10VAC transformers cannot be found, can i substitute with 9VAC? Whould that be enough? 9VAC*1.4 = 12,6VDC

        What about 12VAC? Because I see input capacitors are rated 16V, so 12VAC input would be too close to rated limit after rectification 12VAC*1.4 = 16.8VDC

          9VAC is fine, 12VAC is too high.
