Sansui 3000a updated as per service bulletin?

Howdy all,
I just picked up a minty Sansui 3000a and despite a small amount of scratchiness on the controls everything seems to be functioning really well. Very impressed with the FM reception!
I believe this has had the service bulletin update and I'm going to put a couple pictures here to see if the experts can advise. The fuses are 2 amp and from what I find on the web, that should be one indication that is has been updated. And the two large 1000uf caps mounted on the back also.
Thanks for your advice. I like this one. Still has the blue plastic on the front and it's super clean.
Like I need another Sansui

That's part of it. The diodes should have been changed out on the amp board and a number of resistors changed, added also.

I was fooling around with mine a while back and checked the voltage drop across the fuses, there was some actually. Pulled them out and cleaned up the ends and brackets. Might equal the SQ of $100 speaker wires? Those are really good receivers!

Thanks for the information - I use my son Jackson's AK for him and myself. He is autistic and has EMF sensitivity and he can't use computers or cell phones so I do his computer work for him.
But this question is from me. I can't follow schematics and understand the electronics of these machines like he can. I'm trying lol. He's not doing well right now so he can't look at this for me.
If I send you more pics of whichever boards that should have been modified can you advise me on whether or not they have been?

Appreciate any help. Thanks Jeff
