Need Source for Behringer Parts

[W3KQ]

I need to purchase an IC to repair a DPA400 power amp out of a Behringer PMX3000 board/amp. The schematic identifies the IC as IC4, and the chip is labeled HCA8001 - appears to be an Intersil chip, but not readily available based upon my searches thus far - see this link for a "kind of" datasheet

Datasheet Archive - hca8001 datasheet - hca8001 application note - hca8001 pdf

This unit was a trade at the store, and given the low resale value of this amp, we cannot afford to put a ton of money into it. Anyone have a source for Behringer parts that's reasonable? I found a few sites on the web, but you must know the Behringer part number to order, and our store is not an authorized service center so Behringer refuses to give out part numbers when we call. Thanks for any direction you can provide, Rick Jordan

Try contacting John Frondelli - a member here - at dbm Pro Services in NYC. They stock more parts that Behringer out in Bothell does as far as I can tell. If anyone would have something as a Behringer part, it would be him. Behringer USA itself doesn't generally have electronics components like ICs.

Meanwhile I'd have to say that chip would be a very unusual failure for those amps. Generally it is only the output side that fails. The outputs are driven through optocouplers, so there is no direct connection between output stage and the earlier stages.

What is bad on yours?

I've already check out John's website. He has a big bold header at the top of the parts page stating he no longer has the resources to research part numbers. All orders from his company must be made with a Berhinger part number, so that's the reason for my post. Berhinger wanted to know how I even had a schematic for the unit since I was not an authorized repair center....

Yep, the chip is bad - heat sensitive - will not reset and "unmute" (muting on this chip shuts down the switching circuits - no drive out of the chip to the two optoisolators IC2 and 6) once warm and power cycled - a long cool down, or a dribble of freeze spray on the top surface of the chip restores the unit to proper operation. Already went through the whole process of possibility of chip caps/resistors that were temp sensitive, potential solder connections that were strain sensitive with temperature, etc. It's the IC that's heat sensitive. It's rare, but not the first time I've come across the problem. Sad to say, it's usually the hard to impossible chips that fail. Seems to me there's a law about that somewhere LOL!

Anyway, back to the original question, any other suggestions where to purchase this IC????

Thanks for the reply,

Rick

Send me an email. I may be able to help you with a pull.

Behringer's part number for IC-HCA8001A1B is:

275-94800-10528

The reason we can no longer research part number requests is that we are simply overwhelmed in that area, and it would be really be another full-time job in addition to the parts guy I already have. While the parts business has been good to us, it doesn't warrant an additional salary.

We do NOT stock that IC, and basically because we have never had a single request for it. In addition, it is rare that anyone repairs a PMX3000.

I been referring people to you, John, here and elsewhere. ANy sorts of requests you don;t want to get? people really don;t understand how much time you can burn looking up the number of a dollar part.

Neto from Portugal sent me this web site. One wonders why they can;t do that over here.

Hi John, and thanks for your reply. My post regarding your website statement regarding parts orders was in no way meant as a criticism of your policy, nor disagreement with your reasons. I would imagine it would be highly unprofitable to supply ones and twos of the tens of thousands of components contained within the product lineup (current and out of production) of Behringer (and do all of the lookup and research for them before the order is even (if ever) placed).

Thanks for the update!

Enzo, we will take any and all requests. Whether we can satisfy them or not is on a case-by-case basis.

We have been dealing with Behringer and selling their parts for many years, but the line is now so expansive that it has grown more complex. In addition, they have changed their part number scheme three times over. We are still on the last system with the part numbers on our website, but have an internal X-ref database. I am going to revamp it all, with the inclusion of a shopping cart script, but as to when is now unclear.

Rick, no malice interpreted here. We'd love to help everyone, but there's a lot of mouths to feed out there!
