Well, I put the final cap in this unit tonight and it sounds like the patient may recover. I recapped a lot of the unit, but because I will hopefully resell it, I didn't do them all. The one's I didn't do were okay, so I left them that way.

Replaced the dial lamps, and the pointer got a new red LED as the original was toast. Overall, I am quite happy with it.:banana:

I have some before and after pictures, when it could have been a planter to what I ended up with. :music:

Wow, what a difference. It looks great!

Looks amazing... I love before and after shots.

What type of tools and equipment do you use to clean everything so well? Is there a secret to getting into all the nooks and crannies?

Now that was what I call dusty!:yes:

Beautiful job cleaning it up! :thmbsp:

The X0X0 series is a very worthwhile restore project.

Now another fine Sansui will live another 30 years and somebody will get a very nice receiver to enjoy.

Good stuff. I agree with Crazy: it's nice to see another Sansui X0X0 live on for another 30 years.

I started out with a heavy shot of compressed air from the garage compressor. Then to a paint brush to loosen more up and more compressed air from a can. Then to Q-tips with alcohol, and being anal helps.

Did you notice the aluminum foil on the before shots, love it when people do really stupid stuff.

Nice job, it looks great!

This probably a dumb question, but did you test the caps in place. Can you? Or did you figure out what needed replacing some other way?

Nice, very nice.

My current 990DB project is also a dirty bird and I'm seriously considering giving it the Chomp & Garden Hose wash. It has to be baked in the oven after and I'm not sure I can stuff that 990DB into my oven. :D

Hey, Gretel, move over and make room for my project 990DB, please! :lmao:

A rinse with a spray solution of isopropyl alcohol and distilled water, followed by a gentle blast of clean/dry compressed air would accelerate the evaporation/drying process...

This probably a dumb question, but did you test the caps in place. Can you? Or did you figure out what needed replacing some other way?

Actually, I do it in place first, and if the reading is suspect I de-solder and test it again. Of course I first put a resistor across the terminals to bleed them a bit. Most of the caps were beyond tolerance.

I have put keyboards in the dishwasher before, and some have made it, and some didn't. Not sure I want to actually bathe a unit, but maybe it would work without an oven if you could build a box with a de-humidifier in it. My worry is that water would get into a variable resistor or someplace where it could accumulate and cause damage. Of course if you had a bathtub full of alcohol, you could dip it in that afterwards and it would suck up the water. Course, you wouldn't want to do that if you were a smoker.......:banana:

Nice, very nice.

PaulDo not put the face plate in the oven. The "glass" is acrylic plastic that may soften and distort. I would also be careful with the other plastic parts like the antenna mount, antenna, feet, speaker terminal tabs ect.

Absolutely correct, I just abbreviated the process for my quick reply. I should have said:

The Steps:


All plastic parts removed
no face-plate
no knobs
oven set to a modest 150F or less and turned OFF before you insert the unit.


The idea is to warm it up and let it 'bake' for a few hours to drive out the moisture that remains in tight places. No aggresive heating because you don't want to damage anything.
