Hi All,
We are trying to repair our good old 5002VZ amp. The power supply capacitors need to be replaced. However, it seems that crown used custom parts here. Here are the specs according to what is written on it: BC D7882-0 15000uF -10% +50% 110VDC 135 SURGE +85C MAX AMBIENT 658-0519-301 Does anybody know where we can find replacement capacitors ? Thanks, Rgds |

Out of interest what makes you think the capacitors need replacing? I've never needed to replace any on an Amcron or Crown.
The main problem, as I'm sure you have already discovered is that 110V capacitors of this size are hard to come by as they are a very expensive item to keep in stock, You should be expecting to pay between 100 and 150 pounds for a pair, more at reputable dealers, expect fakes from other sources. Might be worth double checking you need them... |

Wot he said ... I've seen many of these pass through the workshop for repair, I can't remember any of them ever needing a primary smoothing cap changed. Would be interesting to know why you think they are need replacement. I wouldn't rely on any capacitance measuring meter on caps this large, it will probably just show an error.

I have some that might do - if you really need them. You need one more post to send/receive Private Messages. Do that and I can send you photos/info, etc. |

If they are good quality, as used to be back then, they might be just fine and no need for replacements.
My 1970's crown DC300A has original caps and still going strong as well as my many other old amps. Some small electrolytics, small signal transistors and zeners needed to be changed tho. Edited by Tonskulus - 06 February 2020 at 12:33pm |

I just bought one off E-bay, coming from China... Let's hope the packages from china keep coming with this coronavirus going around

More to the point, let's hope they are not repackaging crappy ones in a nice tin, like a lot do with batteries.

That would surely suck....
They're marked as USED and From the picture it looks like they've been pulled from an amp... I'm hopeful.

Well that seller is garbage, he doesn't have them.
I contacted our local crown rep to see if they can still get them but I somehow doubt they do. Otherwise I'll need to find something that fits in there :( Mistakes were made during, the cap received reverse voltage and then released it's pressure in a nice cloud of electrolyte

If they will fit, Mouser sell 160volt 15000uF +/- 20% (Nippon United Chemi-com branded) caps for £22.78+vat each, the caps are designed for use in high ripple current situations (think Inverters), they have an ESR of 14.9mOhms @ 120hz and a ripple current of 15.5Amps. They measure 63mm x 105mm Mouser part number: 661-E36D161LPN153MDA Mfr. No. E36D161LPN153MDA5M Data sheet: https://www.mouser.co.uk/datasheet/2/420/1687836876505b6669848e0-1100623.pdf Edited by APW - 27 February 2020 at 2:34pm |

I'm not so sure 63mm dia will fit. From the e-bay posting I believe the originals are 45mm (dia.) x 105mm tall .. but I will measure them when I get home today I found these on digikey but they are pretty pricy and 50mm but that might fit anyway although at 100v they are under the rating... I imagine it's best to switch both of them - or even better replace all 4 so they're the same on both channels...
I think 63mm might fit if it's not attached to the assembly and I solder some cabling to the board... Might have an impact on air flow though. Either way I need to find a solution Edited by snowphish - 27 February 2020 at 5:57pm |
