NIC WHITE Posted June 19, 2021 Share Posted June 19, 2021 Hello ,my 7800 sound is just a big buzz. I can tune the picture on 7800 and 2600 carts to perfect clarity. I've tried tuning the rf box ,and it didn't help. The sound pot ferrite core is jammed ,and cannot be adjusted. Can I replace it with a potentiometer, or drill out the stuck core???. I have an rca mod kit on stand by ,but I would rather keep the machine original. Any ideas ???. Quote Link to comment Share on other sites More sharing options...
