Hello all,
I recently stumbled across an Onkyo TX-6500 MKII on Craiglist here in Los Angeles for under $100 and snapped it up without even turning it on.
Luckily it powers up fine, all inputs work, though many of the lights are dead so I have a LED light replacement set on the way. The exterior was in good condition but covered in cigarette tar residue, took some careful cleaning to knock down the gunk without removing the printed faceplate letters and numbers.
The lights arrive tomorrow so I thought I'd start cleaning the pots today, they were very dirty and from looking at the top down with cover off I could see this unit would need a decent tear down to get into them. Downloaded the service manual from HiFi Engine and flipped over the unit to remove the bottom plate. Once inside I find 2 puddles under the main caps, one has leaked quite a bit more than the other. Okay, deal with that later, jumped into the pots and switches with Deoxit, opened the sealed volume pot and got it too. All sounds MUCH BETTER, but I do notice that the left channel is slightly thin and tin sounding compared to the right channel, any chance this would be in relation to the leaking main caps?
Did some searching here and found a few other TX-6500 owners posts and gleaned what info I could from their issues. Obviously I need to replace, at least, these 2 main caps.
Here comes the question...
I found these KEMET replacements on DigiKey
https://www.digikey.com/product-detail/en/kemet/ALF20C273EL063/ALF20C273EL063-ND/8681300
They seem to match the spec, a little smaller in size than the originals, but would these work?
I've never replaced caps on a unit, I would put my level of ability at novice so I'm not sure what precautions I need to take with removing the old caps (unplug it 1st...)
Any tips, pointers and LA local tech recommendations gladly taken!
Thanks!
Randy
