NIC WHITE Posted June 20, 2021 Share Posted June 20, 2021 Hello ,my 7800 sound is buzzy and fuzzy ,just static or nothing. I can adjust the 7800 and 2600 colour pots to perfect clarity ,the RF picture pot is also adjustable to perfect clarity ,however my ferrite sound potentiometer is jammed like a mutha !!!. I was thinking about a standard potentiometer like in a guitar for example as a replacement. Also I purchased an RCA mod kit. Would the mod kit bypass the ferrite pot?. Any ideas ???.

+DrVenkman Posted June 24, 2021 Share Posted June 24, 2021 That isn’t a pot, it’s a wire-wrapped ferrite core, and and you really shouldn’t have to turn it much at all (1/8 of a turn probably in either direction). Otherwise you will break the internal coil wires. Quote Link to comment Share on other sites More sharing options...
NIC WHITE Posted June 25, 2021 Author Share Posted June 25, 2021 Yes indeedy ,like the ferrite cores in a cb radio power circuit. However it is now fixed ,and running with the rca mod and new caps too ,so I'm a happy camper. Thanx for replying tho !!! Quote Link to comment Share on other sites More sharing options...
