Darc, I don't see anything glaringly wrong....

 

[derek92994]

Remember when I couldnt solder too well, heres a pic of it, could this be causing problems?

 

[laatsch55]

I don't think so Darc... besides the pop were you hearing any increased hum?

 

[derek92994]

I don't think so Darc... besides the pop were you hearing any increased hum?

No hum, it just randomly pops. About 2 weeks after first output replacement, then 2 days after 2nd output replacement.

 

[derek92994]

Could the main caps have an intermittent fault?

 

[laatsch55]

Do you remember if the bad outputs were in the same position in the column?

 

[laatsch55]

Could the main caps have an intermittent fault?

When they fault even your neighbors would know...

 

[derek92994]

Do you remember if the bad outputs were in the same position in the column?

output 4 the first time then output 1 the second time

 

[laatsch55]

Starting at the bottom of the amp?

 

[derek92994]

Starting at the bottom of the amp?

No, numbered top to bottom

 

[laatsch55]

OK....

 

[derek92994]

There has been no issues running the spare amp, I also run it off the PL pre but i need to run an earth wire between the 2.

 

[laatsch55]

Joe, what do you think??

 

[laatsch55]

There has been no issues running the spare amp, I also run it off the PL pre but i need to run an earth wire between the 2.

Why?

 

[Gepetto]

Why indeed...

 

[Gepetto]

Have you just run the amp with no pre connected for a long period of time to see if anything repeats?

 

[derek92994]

Why indeed...

because i get low level noise when running the pioneer vsx 9500s off the pl 3600 pre

That is not good...

No. Do I have to sit it in a silent room and listen for any component failing sounds?
