Managed to finally acquire correct on off push-button assy replacement as well as the new button cap (which was all I needed) for my MXR 130. Also used a small section of Alien-tape to secure the front control panel, could not see how it was factory installed. Did manage to lose the 6 cabinet cover screws and now need to find suitable replacements before I hook up my entire entertainment system. Ordered 8/36 1/2" that did not fit, close but would not thread in. The MXR-130 will be the center of my audio setup. It will have a Denon DP-200USB turn table, Polk XM tuner XRt12, CD, MD, dual Marantz PMD300CP cassette, Pfantone SS-2 pre-preamp(for my turntable MC cartridge) and a Harmon Kardon BTA10 bluetooth(modernize .. aux input?). Have an input switch box which may be kind of "dirty" and a Marantz AT-6 audio digital timer I was hoping to fit in if I can figure out how to use it. 2 sets of tower speakers Kirsch and Advent .. will have to see which sound better. Need to acquire clean hookup wiring though I have the Monster cable I will use for speakers. Any helpful input apprecated
