Sonic Craft capacitor matching levels
 
Could you please explain the 3 different capacitor matching levels available from Sonic Craft?

Jeff Glowacki 29th October 2014 12:35 AM

Hello,

First, did you see the explanation above the selection field?

>> "Our precision matching is in "pairs" only. You may request a larger matched group, but it may not be possible. Occasionally, we can not find a matched pair. If this is the case, Customer Service will contact you. We offer three levels of matched pairs: L1-factory tolerance 1% matching; L2-1/2 factory tolerance 1% matching; L3-1/4 factory tolerance 1/2% matching".

If so, could you be more specific about what you do not understand?

Thank you.
Sorry, I had not seen that explanation but thank you for posting it, I appreciate it.

Understand fully that this is an old post.
As a newbie, I found it by googling the same question this OP had.

I did read the blurb reprinted in the second post (above), but do not understand the terminology following "L1", "L2", etc.

Can someone explain?
Thanks in advance.

Hello,

L1, L2, and L3 in the context of this thread only pertains to component matching at Sonic Craft, Inc. The OP apparently missed the explanation directly above the selection field for the various levels of matching. Once reposted here, he understood.

If you are finding the explanation of matching a meaningless blurb, it would likely be easier to directly address what you are looking for. If you are not looking to buy matched components from Sonic Craft, the nomenclature used here is meaningless.

So, what parts are you looking for?

Let me try to make this clearer.

I did NOT miss the "blurb" while at SonicCraft. I read it, but, as I wrote, the terminology following "L1", etc., doesn't mean anything to me. So I googled it. That brought me here.

I need to understand it, before deciding what level of matching (if any) I want.

Thanks for responding.

Yes, please. I think it would be if you just told me what you are looking for since the simple explanation above is not registering.

I never said "you" did.

My apologies, I thought you were referring more to the L1, L2, and L3 which are merely a convention for us. Not some kind of standardized matching level. I initially read your post as you did not have trouble understanding the criteria until you read the blurb here...

An explanation of our matching will not allow you to decide whether or not you want matching:confused: Unless you are having trouble understanding the listed factory tolerances...?


I really do not think I could make it simpler, but I will try. You indicated that you did not understand the terminology beyond "L1", so I assume you understood everything before it. It is important to list the present explanation as the wording has slightly changed since 5.5 years ago. It has not changed in the past few years: "Our precision matching applies to "pairs". You may request a larger matched group, but it may not be possible. NOTE: capacitors and precision matching are priced and sold individually ("each"). Occasionally, we can not find a matched pair. If this is the case, Customer Service will contact you. We offer three levels of pair matching: L1-factory tolerance 1% matching; L2-1/2 factory tolerance 1% matching; L3-1/4 factory tolerance 1/2% matching"

So, you understand that we charge for this service per each part. You understand that the matching applies to pairs. I assume you understand a pair means two. L1 matching supplies two parts within factory tolerance, and within 1% of each other. L2 matching supplies two parts within 1/2 factory tolerance, and within 1% of each other. If factory tolerance is 5%, both parts will be within 2.5% of the listed value. L3 matching supplies two parts within 1/4 factory tolerance, and within 1/2% of each other.

It's unfortunate that you seem to have read some sort of tone/attitude into my response (#6) above and did all that unnecesary typing.

None was intended.

The good news: your last paragraph explains it.

Jeff Glowacki 8th February 2020 12:29 AM

You lost me. I sensed no attitude at all until now. However, you are right on the good news. Your query would have been answered faster if you would have just contacted us by email from our site. In that case, I would not have had to type anything ;)

Now YOU lost me.:confused:

How answering here involves typing and answering an E-Mail does not? :eek:
