Happy 4th of July. God Bless America.
I have a Kenwood KA-9100 Int Amp I'm getting back up to speed and have an issue I'm trying to run down.
Issue: Pop in Loudness Switch when moved back to center from either up or down. No pop when moving the opposite (from center to up or down) The Right Power Meter jumps up at the same time.
Same issue with the Monitor Switch when switched to either Monitor 1 or 2. Pop in right channel and right power meter jumps.
When Volume Control is turned counterclockwise to No Volume the right power meter jumps right at the end.
This only happens when there is input from any source. No input...No Pop
Controls have been cleaned at least twice.
Tested as PreAmp Only, and the issue is present in PreAmp.
When Mode is set to Reverse the issue moves to Left Channel.
When Mode is set to Mono the issue is present in both channels.
The Power Supply board has been recapped. No other work has been done.
Looking at the Block and Level Diagram I suspect either the Flat Amp or Tone Amp
Any suggestions would be greatly appreciated.
Thanks........Jim
