That is a duplicate schematic to mine By G. Randy Sloan. Alinear output can be obtained with a LM3914 inserted in place Of the LM3916. This circuit works on 15VDC & 12VDC due to ZD1, R3, & C2. For you needs See if you can find Texas Instruments Application Report SLOA058 - November 2000. A Single - Supply Op-Amp Circuit Collection. If you need I can upload it in Cute PDF format for you all to copy. Just say the word. Thankyou all for advise and input. Addition capacitors a go due to decoupeling needs.
