Default 30 year old Onkyo find works perfectly!


Found this Onkyo TX-5000 in someones trash a couple weeks ago. I recognized what it was from two blocks away. It cleaned up beautifully and works perfectly!

I drooled over these older Onkyo receivers when i was a teenager and am so happy to have one now.

My father has an old Tandberg (still working but scratchy/static sounding knobs) I may want to grab it one day... and i do see some of the beautiful old Luxman receivers on ebay all the time.

Just sharing my lovely find!

Default Alcohol?

It uses to dilute paint and to turn some transparent plastic with white colour..opaque, not more transparent.

You were very lucky... i suggest you to use alcohol to clean glasses and into electronics to clean board solder flux..also to medical purposes.

Yep..some use to be drunk too....hic!

You're twice lucky..to find that unit and to use alcohol without damage.


Sorry, Brazil only to be sold... top secret ultimate schematic, not to share...encapsulated VAS:

Nice find! I love old school stuff as well.

Alcohol shouldn't do any damage to paint or plastics. It does attack Plexiglass aka PMMA, though! Never use acetone, methanol, petrol or anything clorinated to clean plastics or paint.

Edit: With alcohol, I meant ethanol. Rubbing alc is AFAIK propanol?

Nice find! I like the old Onkyos, I have a TX1500 that I got for free. My mom bought it brand new and my parents stopped using it when they "upgraded" to a newer bookshelf system. I happily took it off their hands

According to Wiklipedia, isopropanol is often called rubbing alchohol althou it is medically defined as a specific mixture of ethanol + water.

I go thru a lot of isopropanol. Also good is water and a microfibre cloth.

So it's indeed isopropanol. Hm. I think it's even less agressive than ethanol.
