scratchy sound from tweeter

Hi everybody reading this. Love music but have not a clue about electronics. Since my arthritis stopped me from playing piano and guitar I now listen to vinyl from my old vintage system. Fisher Studio Standard - CA-880 and small Relistic minimus speakers. I bed you laugh now but hey - I am on a small retirement budget.

Sometimes I like to crank the music up (loss of hearing helps doing so). Now a problem occurred while listening. Mostly the left speaker makes a scratchy sound especial when volume goes up.
But there is also a bit scratch in the right one but about 90% less. I changed to wires to reverse left and right speaker to check.

I first thought it could be the 1980's amp condensers. (They might could benefit from a replacement too)
Since the left speaker was observed to have a problem I changed the tweeters in both speakers.
But the problem is still there. It feels when the amp gets warm it increases the scratch.
Question: Is it possible that only the crossover in the left speaker is bad ???
Thanks upfrontPuu

You know, if those are ferrofluid tweeters, it is quite likely the fluid has vanished, and the coils are covered in gunk. 

See if those speakers were in fact ff tweeters, in which case you can do the repairs yourself.
