You musta missed where I said "try to keep it simple for me". <br /> <br />[quote]QUOTE: <i>Originally posted by mark_in_utah</i> <br /><br />The higher value capacitor will improve the lower fequency response, but will not increase the volume at higher frequencies. You don't even have to remove the old capacitor, just attach the new capacitor across (in parallel) with the old one. <br /> <br />If you want to install an op-amp, you've got some serious work ahead of you. <br /> <br />1. Create a stable and smooth DC source. Op-amps require a positive AND a negative source, with a ground / neutral reference. There are other amps that do not require the dual voltage supply, but they require a series capacitor in the speaker leads. For the DC supplies you'll need a couple of small bridge rectifiers and small capacitors. Just be glad that the DCC signal is at a high frequency and basically a square wave. <br /> <br />2. Breadboard up the circuitry, and stuff it into your small space. A standard 741 op-amp is on a 8-pin DIP, and requires at least 2 resistors to make it work. It also wants 10-15 volts positive and negative. This may also drive the need for a couple of small voltage regulators. <br /> <br />So, how's your O-Guage train doing now??? :-P <br /> <br />Mark in Utah <br />[/quote]
