Latest move of mongers selling me crap: they block me from further buying!

Seller not accepting your bid
Unfortunately, the seller cannot accept your bid on this item. This can happen for a couple of reasons. For example, the seller may be limiting how many items you can buy from him or her in a specific time period. Learn more.



to be continued.....

Did I understood correctly???
They have such an excellent customer service which prevents them to selling you crap???

I wonder on what business model this is happening?
Or did they find out that you are going to reveal the fraud on a forum like this? In that case, they are pretty clever....

But anyway, you should be thankful.

Yes I gave negative feedback on Ebay on various occasions.
Business model? This is the world upside down. 1st law of salesman: customer is always right
:grin: .

The OPA603s did work as IV but the sound was not what I expected. I have two genuine OPA603s bought from Digikey to compare.
Seller was quetching sound is normal? Does not get warm in normal operation....
BIG BS!
An OPA603 draws 21 mA, do the math.

Finally I got the splendid idea to ground pin 1 or 5. Sound muted immediately!
In OPA603 these pins are NC, so nothing should happen. That convinced the seller and I got my money back. :)

What worries me is these ICs are laser engraved and look brand new.
:blackeye:

Probably some restamped TL072? :finga:
Why would you want to buy from them again?

Yeah, I have given up buying ICs and second hand cameras on Ebay.
Nothing but trouble :(

Never bought anything from e-bay. However I registered and tried to bid on a vintage Pioneer CDP...the same minute another "bidder" appeared and outbided me...what a coincidence! I said 'minute' but actually it was rather instantaneous. After 3 attempts on this item I realized that this kind of game is not for me. Basically you're lured into buying other people's overpriced crap with no guarantee other than their honesty - measured in tricked % , what a joke :shock:

You can have better deals at your local junk store, in one case I bought an impecable Magnavox CDB473 for 4 CAD (includes taxes, shipping and customs :D ) and the lady even let me test it before.

In the case of OPA603 with 30ohms inputZ on -in there are only 0.5ma of standing current in the input stage. Should be ok for closed loop IVs but obviously not enough for open loop style use.
In Elso's photos the BB and the sides of rectangles are kind of too skinny. Anyway they look like a standard set of characters...

Sounds normal.

Suppose you bid 25 euro and the last bidder was 20. The new price will be 20,50. In case anyone bids 21, the price becomes 21,5 as you are prepared to go to 25. So you will be overbid instantanious indeed in case the previous bidder was prepared to go higher than your offer.

I had little problems with stuff i bought from ebay or from the local version of it. Very little.

I only bid in last 20 seconds to avoid bid war.
My experience with Ebay is very mixed.
I had various fake ICs, TDA1541s that got too hot to touch, no sound, several ICs sold as new but soldered before etc.
I had so far received 1 half defective scope, 1 defective Rollei camera, 2 defective Leitz lenses, 1 lens not received lost in transport....
I most cases I got my money back after some hassle.
Best use Paypal to pay to be protected!
Even a seller with 100% positive feedback can turn out to be a PIA when you have a problem!

Hi, I don't see how you can use a OPA603 open-loop style. It's not a AD844. Anyway I went back to AD811, has very low input impedance at inverting input.

Are there any REAL TDA1541's left on FleaBay? I have all I need but I suspect you are really taking your chances buying one out of China. :grin:

Regards,
Dan

over here we don´t have too. Go to the second hand shop and enough cd players in stock from philips with a 1541 (hard to find one without :) ). But don´t expect crowns or so.

Elso you're right, this one cannot be used 'open loop', I did not look past the input stage.

That is if it's the real deal, I wonder what other 'genuine articles' are on offer from that seller...
