I have a Sherwood FM tuner s-3000V with the MPX in the unit with a copper plate and adjustments,   I have had this for over 10 years.   I did a upgrade on the electrolytic caps that was in a can  60,60,40,10 was the microfarads.   I removed it and replaced them with axial caps and when I was done and I listened to it the sound was much more open, it sounded great.    Over time I wanted to get it aligned so I sent it to someone to aligne it.  Well I got it back and it was clear but the open sound stage was gone as he removed my caps and put a can back in.    Now fast forward to today and I decided to replace the caps again to get that great sound and when I was looking at the unit I found that the person had replaced the 

60,60,40,10 with a 40,40,20, can cap and tied in a 68 microfarad cap with the 20 microfarad.  He tied two circuits into one.  I change the caps back to origninal specs and now I cannot tune in any stations, its like nothing is out there.   

 

MY question is was the fm alignment messed up when I replaced the caps back to spec.   I do not do alligments but suspect that this is the case and now I should  either look for someone to align the tuner or buy new caps and put it back to the way it was  but with better caps.   

I have included a pic of the tuner with my upgrade.

Any feedback would be greatly appreciated.  

Regards

Joseph
