Sansui 6060...harsh sound

Hello

I have a sansui 6060 that I got from my father. It hasn't been touched in a few years but was working last time. I plugged it in and powers on fine but when I hooked it up to speakers a very light scrambled sound came out, like a very faint sound. I tested the fuses and the 3/16 a were blown so I replaced them, but now it's the same kind of noise but louder. Any idea what this could be? Any help would be appreciated!

Thanks

What are you using for a source ?

What input is that source connected to ?

Are there pre out / main in connections ?
Are the jumpers present ?

Is the tape monitor engaged ?
 
I'm using a Logitech Bluetooth adapter and I have it plugged into aux. I don't see anything with pre out/ main in and the tape monitor.

I woiuld start with a thorough cleaning of ALL the pots and switches. There are several articles here on AK that will point you in the right direction.

No inference or implication intended, I didn't name the thread

Agreed ^^^^^

Vintage gear is seldom plug and play if it's been sitting a while. Start with disassembly and cleaning. Sometimes just exercising all of the buttons, knobs and switches will do the trick but it'll more than likely need a full de-oxit treatment.

There is a tape monitor button left of the tuner knob. Also make sure the muting button is off and you have the selector to AUX.

Would crc qd electronic cleaner work? Deoxit isn't anywhere around
CRC QD Electronic Cleaner
 
It's not a cackling sound is it? There is a problem with some transistors on one board that make it crackle like that. There is a thread on here with all the info
you need to those if you need them.

A good thought, but one step at a time. One should always start by cleaning all switches and pots before going deeper. No sense starting to replace components before making sure it isn't something simple.

CRC QD is a very safe and effective cleaner and you should be able to find it at most auto parts stores

I never said it isn't safe, it is made of alcohols and refined petrochemicals and there is nothing in it that will remove oxidation, which is what usually causes controls to be dirty. It will disperse oils and wash away dust, but not remove tarnish from silver contacts like Deoxit will.

Finally got my deoxit, what exactly should I be spraying?

Remove the cover with the power off. Vacuum out all the dust you can, using a toothbrush or acid brush to dislodge dust. Locate the controls and, one by one inject the cleaner into any opening in the body of the control and then work the control back and forth 30 times. Do all the switches and the volume, balance and tone controls. Any excess that gets on the board should be wiped up with a paper towel or Qtips and alcohol. The tuning capacitor should be cleaned, but not with Deoxit. The instructions are here:

Tap on the speaker relay with a non metallic probe, like a plastic pen. If one or both channels some back, replace the relay. the part number is on the case of the relay. Digikey stocks the relay. If you can't find the relay at Digikey, post the part number and we'll help you.
