Re-curbing the amp , all caps seem visually ok, amp hits distortion at vol level 3, any input. Using aiwa 6 ohm speakers . Any ideas

how old is it?
maybe the main smoothing capacitors have dried out.

o.k. - 30years minimum - probably main caps.
here's a manual:

I was given an Aiwa Z-R700 from the 1990s era to look at by someone who said the twin tape deck did not work. The whole unit unit powered up ok but there was nothing from the tape deck. I had a look and found all the belts broken, I replaced the belts and then put the tape deck back into place and it still does not work. Also when I now power up the unit all the lighting on the front is very dim and the cd player and the tuner as well as the tape deck do not work. I have checked all the connections and ribbon cables again, there are no burnt or swollen capacitors. Maybe there are capacitors on... -

Hello all, Aiwa TX-110 Tuner got out of storage and the buttons was held in by some gloop, What glue would you use to restick these buttons (they are no snapped off)
Thank you -

Good guys.
I have this problem with this Dell notebook, it has that distortion on the screen as you can see in the photo. has it ever happened to you?
I present the tests and measurements that I already did:
I tried with another screen and it does the same thing, I also put this screen on another one and it looks perfect.
I checked the LVDS flex that goes to the display and it is perfect
Through HDMI output the image looks perfect
All power lines were measured...09-29-2023, 06:46 AM
