I'm not sure what R-9/C1 is. I don't have a schematic.
Does anyone have a schematic that can identify these parts?
Hi Thomas,
In my post
/g/la1k/message/1311 you will find a link to the FCC.gov page that has a list of documents relating to the LA-1K.? Click on "Users Manual 2" (bottom of that list) will take you to the initial-released copy of the LA-1K Technical Manual as submitted to the FCC for consideration.? On page 14 of said technical manual, you will find a "LA-1K BLOCK DIAGRAM" which is the closest thing to a schematic of the LA-1K that I could find, since acquiring my LA-1K brand new directly from Palstar in January 2023.
I understand repair action of your LA-1K to be remove and replace of R-9/C-1, but has Palstar's failure analysis determination successfully identified the root cause, that Mark Ward (Palstar technician) told you he will "identify what the root cause is" as I read in your post
/g/la1k/message/1423 dated September 28, 2023?? If so, has Mr. Ward shared with you the root cause in question?
