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

Thanks so much to you all here, I feel blessed and like to express my gratitude!

I tested the speakers with a 9 volt battery and reverse polarity. They pop in and out without any noise besides a static crack when connecting.
Next thing I will do is to test the Fisher with different speakers. Have to drive two hours to a friend and will update my testing here.

Thanks for the suggestions, that fit my budget . Since a work injury took me down 13 years ago  - I shop @ thrift stores.
In my old working life I rode a bike an skipped a car, this way I could effort a Linn system (LP12, LK1 LK2 and Linn speakers) and I was a happy camper for many years.
That life is gone and I miss parts of it. But the CA-880 made listening to Oscar Peterson "You look good to me" still a pleasing experience, clean and a bit punch. And yes, the Realistic speakers lack a lot and I came close to add an SVS sub to them ( I hat to let go of a "housing only" damaged pair for a great price due to high shipping cost).

HI ALL,
Mahalo for your input!
I tested the receiver with headphones and different speakers - all is fine.
Anyway, after a long music journey (like many of you may have done – the first “furniture” to plan to position in a new home where my speakers) I now consider to slowly upgrade my baller system, starting with new speakers! (Guess I am still hooked and I miss my old Linn system remote as a comfort queen)

Well aware the budget guys pay always double; I have to wrap my head around replacement, the $ 60  Dayton Audio B652 and add a Dayton sub or yield at the Pioneer SP-BS22-LR for $100.

A bit much, but I would love to yield at the ELAC Debut 2.0 B6.2 for $277.00 a pair or the KEF Q100 for 320.00. Never heard them and wonder if I can trust the hype.

The Ca-880 has no special sub connection to put out the right crossover signal (hope I say this right?) and I question how the ohms for sub and speaker will be ok fro the CA-880 and future amp.

MAHALO & ALOHA

Here I go...

Andrew Jones did a great job on this speakers and thanks to all of you for that suggestion. I am not a Steve Guttenberg and according to E. Hoffman: "Music And Brain" everybody listens different. With plenty of different music and listening (break in my ears) for a month now I can say:  The best $ 100 I have ever spend so far.
But - these speakers are very sensitive to positioning. Therefore I decided to look for speaker stands but I was not able to find something pleasing under $ 300.
I  found some old Hotel lights made from steel with cast iron foot at a recycling shop and modified them to speaker stands and gave them even rolling feet and sand filled everything hollow.
Now I am a very happy camper from classical to rock.

Yes, you get more than what you pay with this speakers. And yes, a sub I think would be a nice addition. And my 80 watts amp feeds them all nice to a volume of about 40%. If I crank it up more the speakers start to react with distortion. But 40% is more than I need since I mostly go with 30% volume.

Over all: My kudo to the designer. It costs no effort, not much money to be in AWE. Listening to this combination is not just consumption but imagination, very satisfied.Thanks again
