Rittenhouse Service & Repair Forum
Existing model was put in my home maybe late 60\'s, with ivory base unit and 4 ivory receivers plus brass door unit intercom. The radio reception is irregular, fades in and out and there is much static. Sometimes have to jiggle knobs on base unit to tune radio! Any suggestions on where to go for upgrade/ replacement and cost range? Thanks much.Mickey
