Hi kids.
Newbie here and i thought i try my luck on this board.
I have a Technics su v-60 i bought in 1986 or 1987. Used it constantly for more than 10 years , moved to a new place so it got stored away. Took it out awhile ago , new speakers, the old Jamo beasts had to go during the move, unfortunately. I use a Macbook and Iphone as the source. I love the this amp, its my youth with all memories, i refuse to go buy a new amplifier.
Now, it has a terrible cracking noise 80% of the time, one speakerchannel is more or less gone when i turn the balance. I´m struggling to find any clean sound as its cracking and dropping basically all the time, but when i do find a window without the cracking its a wonderful sound.
I do like to think its worse in CD-direct mode, but it could be my imagination. ( i never really understood the CD-direct function as i mostly used a turntable. If anyone can explain it would be nice). Theres also the subsonic filter button , which i think overrides the bass and treble? Or is that the Loudness? Its been awhile since i used this old friend.
Today, for the very first time, i took off the metal cover and the inside was all covered in dust. There was also a weird burn mark in the middle of the (inside) cover, right above the classAA sign of the front.
I googled about cleaning, bought the CRC-electronic cleanerspray.
I don't know anything about electronics and tech stuff, so my question is if you have any idea what to do about these problems. The only thing i´ve done so far before this post is wiped off some of the dust with a cloth and sprayed a little on the balance pot meter and worked it. Its still sitting with the cover off.
I realize it would propably cost too much, even if i can find, someone professional for this so i´ll give it a shot here.
Any help would be very much appreciated.
Would pics be of any help?
