Thanks to Dennis for all his effort in the group buy. Got the chips...now to actually do something with them.

I used LM4562 on some of my collected decks (Revox B215, Nak 700ZXL etc) without very prominent changed in sound qualities that alert you wanting to shout out 'wow', there is some magic in this opamp....

But I did try LME49710HA(TO99-metal can) in my Sony CDP-557ESD subtituting the 5534 (the audio buffer out) and the result is unbelievable encouraging with some magical spells that you have to try to believe. The most significant change at the first instance you turned on the player is the vast improvement in the bass region (lower,deeper,more control, more definition,more slam...) that enchanted you to keep on listening as if a higher musical nirvana
is reached.

Can someone guide me as to where can I get hold of 1pc LM4562NA or LME49720NA - DIP-8 ?? Just want 1pc...

Thanks!
Dennis Hui
I still have some LM4562 DIP-8 parts left over, but it
probably doesn't make too much economical sense
to mail out just one (too much for postage.) Still,
if you can't find it from a closer source, by all means
email me.

Cheer,
Dennis
arupg
Thanks Dennis for responding and your offer. I'll let you know and just incase I may need 1pc, pls save me one.

If there's another GB happening I'd probably want 6 SOIC and 4 to 6 DIP.

Hi Jopie,
Do you have some good news for us ?
Nice to hear from you. ;)
Gulfstream
Hiii All

This is the latest news for LM 4562

As first time we order at digikey Singapore
Because they werent available the LM4562
(They give us answer, 12 days after order)
so we must order from digikey USA

For not increase the price (30% taxes in indonesia)
so Si Jopie ask digikey sent this LM to his friend in PA, USA

The LM 4562 has arrived 2 weeks ago from digikey
as i known si jopie order when ttr need his email
the latest (maybe) some procedure in digikey himself

Now, as i known our address and quantity needed
have to sent to his friend and i hope everything
must be posted to your address but it is depend
on his friend service

This is the news what i have when i seen him
Very sorry from si jopie for lateness
and his hope all the LM will arrive soon

regards, jeffry
Praudio
Really not serious this group buy; first and last time !
subterfuge
OK, let's see if I got this right. The first order of chips from the Digikey Singapore didn't go through because there were no LMs available. It seems I missed the report of that.

So then these chips were ordered from Digikey USA, and in order to keep taxes low, were delivered to somebody living in there. I had no idea of this either. And now that person should have all our addresses and has been sending them out all over the world, correct?

Or is that person still debating if s/he will collaborate ("it is depend on his friend service")...or what?

In any case, these chips would now arrive about a month too late for what I planned to use these for. I have to make an another order for myself, and unfortunately they are not going to be LMs either, not with our local prices and availability.

Well, if these LMs ever appear here, maybe there's some other use for them, somewhere. Too bad, the initial deal was pretty good....too good?
theAnonymous1
Subterfuge,

Where are you located? I think I have 6pcs. of LME49720, which is identical to the LM4562. Perhaps you can substitute the other 12 you need with OPA2134 for now (I have plenty of these).
housing
I have just written to Digi-Key enquiring about the shipping cost for 120 pieces (3 tubes) of LM4562 Dip-8 to Hong Kong. If the shipping cost is not too high and the last group buy has proven to be unsuccessful, I think I can take this up provided interested members support me to do so.

:)
subterfuge
theAnonymous1, I really appreciate your offer, thanks. Unfortunately 6/12 won't divide easily with my projects as of now...
allthough, because of all the delays recently, not just this one, I had to do some new plans and re-scheduling anyway.

Housing, thanks for your possible help too.

I quess what I would like to hear first is one solid Yes or No from our Jopie or friend. Could help proceeding with anything related.
korben69
Hi all,

Sorry but I can't understand who's selling what...
Why si_jopie0382 can't give us some news ?
What is the expected delivery delay ?
I'll claim Paypal for refund if no clear position is given to us shortly.
I can understand and be patient but, the less we can hope are some reliable informations... don't you think so ?
loek
So far i did not pay anything to si_jopie0382 for this, he only asked my name etc.
He wrote:
Payment detail is simple and easy,
No need to pay me first, after i send the device to you i will send an invoice using paypal to your email and the last thing is pay me after you received the device in good condition.

It is strange he does not reply for himself either....
Nice offer housing, i will wait the result of your findings.

I have received the reply from Digi-Key. The shipping cost to Hong Kong is around US$70.- The reply is accompanied by a series of questions on Company name, final destinations, usage of the IC's........etc in order to comply with the Export Law of US. The reply date is due by mid-March.

Strange! Strange! I've never encountered such hurdles when I ordered parts from Mouser.

:D :D

I will proceed further provided :
1. si_jopie0382 explicitly express that he will abort the last group buy.
2. Members show interest to consume at least 100 IC's.
korben69
Yes Loek, you're right, it's my mistake, I've paid nothing at all.
Sorry for that, but can we hope some news ???
Praudio
What we do now?:confused:
housing
Digi-key International Sales has sent me a second request for buyer's information and I decided not to reply. It seems to me that there's little interest from members in this group buy, and I think it's appropriate to drop it rather than holding tubes of IC's in my tool box.

:) :) :)
jean-paul
I am in but I lack time to organise things. If you want to do the group buy just send the people from the list a Paypal request for the money. Those that wanted the chips then will want them now too.
JonHarrison
Hi,

If someone is reopening the group buy I'm interested in some !

Cheers,

jotom750
As this group buy seems to have hit a wall, in spite of many good efforts.
I have been communicating with an E’Bay seller , “semielectric” I have bought from him in the past.
he says he can supply and has in stock LM4562 . 8 pin dip.
120 at $3.90 each + shipping (approx $20 for 120 batch within USA).
He will only keep this price if 120 app are ordered and posted to one address, USA preferred.
Is it possible that a DiyAudio member in this GB can then forward them to others.
Hope this helps.
Dennis Hui
It's too bad this GB seems to not be proceeding well.

If there is still sufficient interest, I will volunteer my
services for another round.

Cheers,
Dennis

But digikey quote $2.62 for 100 ? Even with VAT at 17.5% that's only $3.08.
theAnonymous1
I still have the 6pcs. of LME49720 available if anyone here is tired of waiting for a group buy. I would prefer to sell them all to one person.

$20 for all 6 pieces. Free shipping US and CA, $3 ROW.
jotom750
Hi.
Yes $262/100 is great. The original GB price for this was,
Quote:-

I try to make it simple.....
Price is $4.5/pcs (paypal charge and shipping cost incl.)
but minimum order is 5 pcs.

Shipping is free on orders of over £100 ($200)
I think the other adds were due to PayPal & shipping
of individual orders to members. Quite fair I thought.

Note- today price moved from $262 per 100 to 289 per 100.
theAnonymous1
The LME49720 are now sold.

Thanks
JonHarrison

Digikey.com is showing $262.45 , Digikey.co.uk is showing £289. I'm interested in 20, anyone in the UK want to make up the numbers ?

Jeffry,

Do you know what actually happened with Jopie's
order? The last update seems to indicate
something had been ordered and shipped. :confused:

Again, my offer from a few posts back still stand: If
there is still sufficient interest, I can volunteer to
do another GB.

Dennis
subterfuge
Yes, indeed...wouldn't it make everything just more like a good old mess if we all of a sudden start to receive these chips we have been waiting for so long, and there would already be a second round ordered?

It's not necessarily the lack of interest why people are not lining up for another GB, but more like confusion of what is really happening with the old one.

Since the original organizer has been curiously silent ever since, someone has to make initiative. The first thing is to clear whatever has been hanging on, so let's just do that, shall we?

I can start. I will NOT be a part of this last GB anymore. I will wait one more week just to get any possible late note in, otherwise I'm out as of now.

I will consider a possible new GB after this last chance period is over, although my original need is already gone and done. Maybe few chips just in case, we'll see.
wckong
Dear Mr. Si-jopie0382,

Do not forsake us. Oh! our dear member.
Just one word from you mouth is much better than countless posts form others...
Here we are, waiting for you...time waits for no man!

Best regards!
A'af
Hi,

I just called si_jopie by phone, and got the prbolems he has.

He is a very busy businessman with the real job he has.

He already buy many pieces of LM4562 being order here in this GB, but the shipping from digikey is missed shipment to jakarta and all checked and rechecked about this takes times even to digikey. The result are the items are not delivered and sendback to digikey.

So he made a decision to shortcut time wasted. With helping by his friends to accept this and distribute from USA.

Perhaps his friends not count this deal as we are here, especially to manage GB, really is hard to do! I can imagined his friends confusing about this all about... hehehe...
many names many address and for God sake distribute this little critter to all around the world

And time different making hard to communicate to his friend is not smooth (10 hours diff time)

But i also got the info, his friends already got "what happen" and already post some to you, maybe his friends have got some spare time about this ;)

So dont worry to all of you, in a short time you will be received, what you request here, and si_jopie say pls be sorry for all this.
He also needs the confirmation and the payments later after you received your order, thanks.

Hopes this post, make all "lots of question" clear here... goodluck to you all :smash:

all the best,
a'af
subterfuge
No.

Wasn't it the member Gulfstream who announced pretty much the same thing 25. of Feb (see previous page). Now this.

Whos next to bring the (not so new) news to us, after an appropriate wait of course...like one month, maybe?

Just to keep things fair and open, shouldn't the person actually handling the physical side of this GB finally present him/herself to us and tell the exact situation as it is right now, at least privately? Or are we supposed to just sit and wait while our addresses and all have been tossed around the globe to whoever would like to see and use them, somehow?

And Jopie is still in charge of the payments? So this friend sends some chips by airmail, sea, train...something nobody knows...if s/he will. Then we will receive the chips, if we do. Then we will accept them, if we do. And if all ifs meet, maybe we pay something to somebody. Might wanna buy a lottery ticket too, I think.

Hope the possible package comes with a return address. I'm just so much more out of this mess. Thanks for all the efforts, I do know it's not that easy to arrange even national GBs sometimes. Still, even with just a regular job and extended hours, I'm busy enough too. Things gotta move and happen. Sometimes. Maybe.
Gulfstream
Hiii All

I meet si_jopie in his office this night

I won't accept the package if it has been shipped.
Sorry for that but I've sourced LM4562 by myself...

Silence is gold/golden?
Am I a blind man riding on a blind horse in the mid-night heading for the source of LM....?

Somebody knows for sure?
I am very sorry... for asking too many questions.
