Crown D-75 Power Amp, Pot & Cap
Hello,
I have a Crown D-75 amp that is missing a cap on the on-off switch. Does anyone know where I can purchase one, or maybe something cheap I can squeeze on there? Also, one of the volume pots are scratchy. I haven't tried cleaning it out yet, but in the event that I need a new pot, what kind of pot can I purchase and where's a good place to order from? Thanks, Jimmy |

I'd suggest contacting Crown. Those things are often quite specific to the manufacturer in question. http://crownaudio.com/ Graham |

About any 600+VDC 0.02uf or 0.01uf ceramic disc cap will do just fine. The volume-controls _will_ be specific to that amp, but if you know the specifications, you should be able to find after-market replacements or upgrades. But I would strongly suggest you clean them before you replace them. Be sure to use a *lubricating* cleaner designed for volume controls - or, if you know how to be very, very sparing in your application (flame-suit full-on) WD-40 - after a non- lubricating cleaner such as mineral spirits or the like. Even Radio Shack tuner/cleaner is excellent in this application. NOTE: ALL OF THE ABOVE ARE FLAMMABLE. Allow all volatiles to escape before applying power. Peter Wieck Wyncote, PA |
