Service manual/diagram

Hello, I am new here and I have back (!) my old AX 7500. After all those years I think I have to change some components.

That is the reason I am looking for the SERVICE MANUAL/DIAGRAM. I would be very grateful to the person who could provide it.

Thank you.

Did you look in the database? Click on the link above and try several different ways of entering the data until you find it or determine it's not listed. I had to get creative with my receiver to finally find it.

Thanks, I'll try again!

And I found the AX 7550 manual. That's OK!

Re: Service manual/diagram

Just curious, which manufacturer makes the AX 7550? Is it a reel-to-reel?

Re: Service manual/diagram

The Aiwa AX 7550 is a receiver (1976). I have the type AX 7500. I don't yet know the difference.

Ah, yes I see. The Library (link above) lists the 7550 and it's specs. You might be able to add to the database with the data on your model when you find it.

I had never heard of Aiwa, but looking at the specs for the 7550 is looks like a good one. Decent power (not the most important) but excellent distortion level (anything < 0.3 is excellent) and good damping. Excellent sensitivity and freq response too. Numbers comparative to high-end units.

Take good care of it .
