Default For sale or trade OPA627/637(DIP) and DCX 2496 (2x)

20 pieces up for grabs. All AU series.

Very much prefer a trade for suface mount 627/637.

I have a device which requires 30 of them...but surface mount.. All I have left is DIP (8) package units.

Not really interested in shipping off onesies and twosies. I'd like to get rid of all of them at once, if at all possible. Let's haggle!

And a barely used DCX2496 (or two).

One with mild mods, oscon caps all over the place...and OPA2604 chips here and there (input board), mildly modded PS, etc.

Second unit, nearly NIB, bone stock.

Both with manuals and boxes.

I'd like to know the prices of either one.
Thanks

I just offered a guy in switzerland the slightly modded one for $235. mint, no scratches if you squint and it is in another room. Just kidding. Should be fine. I put a rca jack on it for the digital input, as well. minor stuff. just trying to assess the design to see of it was worth modding out. It is definitely worth modding...but I've moved on.

I grabbed a DEQX 2.6P recently,and the op amp upgrade for it, is going to cost more than the cash I'll get for the two DCX2496's! Ouch! That's with Ti paying for more than half of them....I'm hoping.....I'm calling them now. I have to sound confident and important (ie, with i, knowing what I'm doing, etc).....at the same time I beg. Such is life.

I need..FIFTY OPA627's. All SMD. and 25 brown dog adapters. That's $200, just for the adapters. They work great, though!

The universe has run out of the SMD version of this chip.

HOWEVER, I can get many of the others from the TI sample program.


Will swap dip for SMD versions. (I need SMD, will supply DIP). Or whatever.

Let me know.

Sold most of the DIP chips, to one buyer. Kept three for a guy who wants to trade for 3 627AU's.

Found 5x 637BU smd chips in my pile of stuff!...

looking to trade them for 627AU series.

Both DCX2496's are still available, will likely go on fleabay soon.

Looking for $175 for the 'bone stock' one, I paid more for it when they weren't available..and I left it in the box. It had been previously used for a short period of time by a DIY board member. If you are on this board, you don't care about warranty, you are looking to strip the unit anyway!

The other, I'll let go for $200. Get them out the door! Still have the 5 637BU smd op-amps. Somebody must want those.

If you have OPA627UA chips, I can get you anything in the same series (for the sake of simplicity) as a trade. 1 for one. For example, I can get you 30(x) OPA627AP's or 30(x) OPA637BP (PDIP package) for your 30(x) OPA627UA's (smd's).

If you have them, let me know, and I will get the appropriate # of chips to do a trade with. Looking to do trades in the 10-30x chips only, too much hassle to do smaller lots..however, don't hesitate to throw your chips in the pot, if you have fewer. Like 6 or so. If swapping a smaller lot, I'd prefer it if was done on the north american continent. It's faster in terms of delivery. For example I did a 637/627 swap in three days, for 12 units.

There will be no TI stock replenishing of most of the 627/637 series chip until at least March 15th, that's too late for me..so..with TI's full knowledge, I'm getting samples of other chips and doing a swap for the 627AU's from people who have them.

I'm modifying a piece of audio gear that was obviously designed by computer nerds and pro audio folk. No clue about cleaner, simpler design pathways and methods, or parts quality over 'textbook' implementation of chips and support sructure. It takes FIFTY 627 opamps to fix it. It didn't need to be this complex...but it is...and the 627's will help tremendously, compared to what is already in there.
