Good morning fellas -
I performed an alignment by ear several times which did increase the volume and clarity but did not resolve the underlying distortion. Each component replaced has made an improvement but there's still an issue that I haven't isolated. A couple of those resistors I replaced were past 20% out of tolerance and I was sure was the cause.
I worked from home yesterday but spent the day in the radio shop working on this and listening to AFRS Christmas broadcasts on my 66s. A great time but didn't get to the last two resistors. Kind of got side tracked a few times. One is a 4.7meg but my tester does not measure above 2M. Been thinking of getting myself a new Fluke.
I don't have a permanent magnet speaker to use as a test.
Could the volume pot be the cause, and if so, how to test?
I'm also not entirely sure the speaker isn't the cause.
Regards,
Paul
