Default LCR capacitor instead of AMPOHM FP-CA-AU supplied

I ordered AMPOHM FP-CA-AU 4.7F/630V capacitors (2 Nos) from Element14 India but they sent me LCR FP-CA-AU 4.7F/630V capacitors. These capacitors r not made by AMPOHM but r made by LCR.

Does anybody know whether these LCR made caps r as good as AMPOHM make.

Quick reply will be appreciated, as I have to raise discrepancy within 3 days.

Thanks in advance

No first hand experience with those particular LCRs but i find it strange those would sell at the same price. LCR is an established supplier for industrial caps and some are not bad for audio. Ampohm, otoh, have produced some really great caps for audio and as such command a price premium. Not sure if this helps at all.

I believe Ampohm went out of business some time ago. Perhaps thats why you
were sent LCR. AFAIK LCR caps are pretty good.

By the way I tried some sample Ampohm PIO caps and they were trully
awful. Perhaps thats why they went out of business.

Or maybe the Ampohm's didn't work well in your system/application.

Ampohm have proved themselves in many systems as being very good, so I would be inclined to look for the problem elsewhere in you system.

As to why they went out of business, I don't know why, and neither do you, could have been one of many reasons that have nothing to do with the products.

Ampohm used to make a lot of caps and wound products for the car industry, when that went into decline during the UK recession a couple of years ago they couldn't survive.

Thanks for the info Lee, I'm sure they would not have been alone, the recession hit many businesses hard, some just could not recover.

This is my first purchase of a Polypropylene capacitor. I have no idea how they sound as they CANNOT be purchased locally. If there is no Ampohm cap available, I will have to go with this LCR one, which looks pretty cheap.

I have called the supplier and sent the photo of the cap as requested. Will have to wait for the development.

Ampohm went out of business probably as a result of the recession. I believe that all their equipment and processes were bought up by LCR. So far it seems that they are not producing PIO's for the Audio market. A couple of years ago I picked up 2 pieces of Polyester in Oil 3.9uf, installed them in my speaker crossovers. It took a couple of hundred hours for them to open up but they are hard to beat as I have compared to Mundorf Silver Oils and Jantzen. They will remain in my speakers!
6 months ago I picked up from the Tubestore in Canada 2 pieces of Ampohm PIO aluminum Foil 4.7uf and after quite a lengthy run in the outputs of my DAC they to my mind beat the Mundorfs SIO in musicality. The Mundorfs can be a little too bright in my system, with metal dome tweeters and all.. The Tubestore still has a small stock of Larger value Ampohm PIO's but they seem to be disappearing quickly. Hifi CollectiveUK has some too. The wonderful Polyester in Oil are very difficult now. The last I was able to find was a couple of at 1.5uf at Definitive Audio UK 3 months ago. The Tubestore also seems to have a pretty good stock of Ampohm Copper PIOs in smaller values. Some people I've talked to have said they like them very much. I hope that someday LCR will produce some PIO's, however its likely too small a market to interest them.

The Copper PIOs were said to be their TOTL capacitor.

A real pity they are no longer produced.
