I am considering replacing on old RC4136 quad op-amp with the odd pin-outs with two THS4032 op-amps in a BrownDog adaptor. Celestian suggested using a 1uF Tantalum Cap from pins 8 to 4 and Radian sugessted a more optimized circuit using a 0.1 uF film and a 100-200 uF lytic from each power supply pin to ground keeping the leads as short as possible. If I go for the more simplifed approach from pins 8 to 4 do I need to apply caps to each IC or can i just place one cap from Vcc+ to Vcc- on the adaptor board to cover both IC's? My concern with adding the multiple caps as in Radian's approach is finding a ground point close to the IC socket. There doesn't appear to be a ground point on the adaptor board.The application, for what it's worth, is to bring new life to a vintage Spectro Acoustic preamp. Unfortunately, I don't understand all I know about this topic, so your comments will be most appreciated.
