Sony STR-6800SD Filter Cap ?

[Dorkelstein]

Hey everyone. My STR-6800SD appears to have a 2 section filter cap. If I'm reading the schematic correctly, it's a 2 X 10,000uf @ 63v cap. Are these available anywhere ? Nothing wrong with mine, but a 33 year old electrolytic is bound to be nearing the end of it's lifespan. It would be comforting to know it can be sourced somewhere just in case. Also, I'm not sure what the voltage is in the P.S. so itmayne a good idea to bump the voltage rating up to 70v or so to accommodate modern wall supply. Although I rarely run over 119v at my place. Any ideas ? Thanks, The Dork.

It sure does look like a single cap in the pic but no pic shows it well. Called C901 and C902 on the schematic. It looks like there is room to mount a couple caps to get you what you need, maybe a couple 12,000µF/80V caps will work. Making them fit, look to see if you can mount some brackets since these new caps can be just 35mm in diameter. Lots of other ways but my 6800 departed before I did the recap on it years ago so don't have one in front of me to figure out what to do. The scat shows 53V on the rails so a 63 will work but it is fine to up it some.

Definitely is a single cap. I saw that when I changed the panel bulbs. Maybe room to re-stuff it ? I've done that several times with multi-section caps in tube amps. I used the "Pencil Caps" from Mouser but they're not available in that high a value.

sure restuff it if the OCD makes you do that. Put a cap under the panel so you can't see it.

But there is plenty of room to install a pair of good caps to do the job but you will have a normal looking receiver with two big PS caps instead of just the one dual cap. I can't help with OCD that drives many restorations here into more work but a result that looks original on the inside except for the look of the LEDs many use. Good Luck.

I don't consider myself OCD. Meticulous and maybe even anal retentive. I just don't like work that looks like it's been done by Joe S*** the Ragman .

Then do a professional looking install of a pair of caps in brackets. That might mean drilling a hole in the chassis for the second cap or putting the caps together so that the leads from both can go through the existing hole. Just need to look it over and decide what you want to do. Caps are in series with a wire to the jumper between them and the - and + leads on the other connections on the caps.

I could make it look like it grew there. I still want to try to source a cap that would look like the original. Someone must make them.

maybe hayseed hamfest could restuff that one or build you one.

amplified parts has dual caps but they are much lower capacitance and frequently much higher voltage for tube gear. I've got a triple at 47µF/450V, 47µF/350V and dual caps in a unit at 1500µF/50V and 75µF/475V. Since juice is a combination of the voltage and capacitance these are pretty powerful but your rails are much less than the 300-500 in tube gear.

See what Hayseed has to say.

Great idea. Thanks.
