ulao Posted December 3, 2022 Share Posted December 3, 2022 (edited) Does anyone know the specs on the chroma pot? I tried to clean it but it didn't really help enough. So I removed it and There is no way to open it without out destroying it. Looks like one side the resistance goes up and the other side it goes down. But it is in such bad sahape I can not tell.

8bitAndy Posted December 4, 2022 Share Posted December 4, 2022 Do you mean the controller adjustment pot? I don't know about a chroma adjustment pot. In any case, you could try replacing it with a fixed resistor or a fixed resistor plus a lower resistance pot. Quote Link to comment Share on other sites More sharing options...

+-^CrossBow^- Posted December 5, 2022 Share Posted December 5, 2022 Accept those are only listed to be 500Ω and not 500K Ω as the service manual states. Might see if these will do the business? https://www.ebay.com/itm/134234317909?hash=item1f40fd2455:g:q1EAAOSwn9djI6VW Quote Link to comment Share on other sites More sharing options...
