Unfortunately this is the case for a lot of these cheap Chinese re-badged brands, they are disposable commodities with no service support or spares.

I stopped repairing this sort of kit about 10 years ago as it just wasn’t worth the effort but, I used to do the repairs for a small chain of music shops, amongst other brands, for a while they used to sell Berhinger, I never managed to get a single schematic or part out of them despite being a dealer.

Other makes were as bad, we had a Numark mixer in for repair that needed the faders replaced, the cost of a set of faders direct from Numark was the same as a new mixer and that’s before postage and my labour… I managed to source the components elsewhere for about 2 quid each.  

One exception was Wharfdale pro, the gear itself wasn’t that good or reliable but the service support was excellent, I’d phone the service department for schematics or parts , they would email me the schematics straight away and often send the parts out on a next day delivery often for free, even if the equipment was out of warranty.

Behringer have never given out their schematics. The technician for the main dealer here told me that years ago. They supply the dealers with some spares - and everything else has to go back to the main office in Germany. Odd, but true. They must have their reasons, I guess.

I know... doesn’t mean it’s right though!!!

I have a few iNuke DSPs that get used on monitor duty or for smaller gigs when I can’t be arsed to roll out a rack of QSC’s, they are well out of warranty and if when they fail, they will be landfill as I’m in no doubt Behringer will not repair them being that they are now a legacy product!! When they do eventually fail (and they will!!) they may well be repairable however without service information it’s just not economical to do so.

I have in my lockup a few Crest V series amplifies and that are 25+ years old, I have schematics and all the parts are still available, I can keep these serviceable almost indefinitely…. And I can still repair old valve amps and industrial equipment that was made before I was born!!

Behringer’s justification for not releasing service info is that their equipment will be copied, this is rich considering that their early amps were blatant copies of QSC amplifiers.

Edit: I was typing when you posted above regarding coping!!

Yes - the throwaway philosophy/culture is BS, I hate it too.

Most of my amps are also old school - mainly Crest as well - 7001 and 8001. They just keep giving!  LOL Clap LOL

Probably because if they released their schematics to non-NDA covered personnel, various patent lawyers would be VERY interested!

Your Dad is a top don by the way. Care to elaborate on what he found wrong and fixed? I bet it's a common fault, might even be the one that kills them all?

LOL…. This exactly the conclusion I came to as to why they never released the schematics!!

Had a mackie profx8 in for repair recently,had it in before for a minor repair so I knew it’s a bit of a pain to work on but with nothing else happening,I said I’d would give it a shot.

One gain pot physically broken and two other dirty as well as a couple of diodes gone,

Went to order new pots from loud technologies and found that they don’t stock them anymore which is shit as the mixer is still a current product.

None of the standard component companies had a matching replacement so a long wait until Ali express came to the rescue 

Companies these days don’t make it easy

Right to repair or guaranteed support for a fixed term or repairability ratings or some mix of the lot needs to come into force. The current "its tough, buy a new one" is not sustainable,  responsible or necessary really. Hopefully it will drive new economics models which will have knock on effects for design.

Wishful thinking, but lets hope...

100% agree with this. For a company that should hopefully be sustainable and support climate change throwing a product away regardless of cost for a component worth pennies available from RS is ethically wrong. Why shouldn't products be maintained, as in previous years? Its all about greed and profiteering. To put things into perspective, it's a 4 channel £450 amplifier that serves a purpose. The fact that I've had 3 new amplifiers since 2017 from thomann (1 new, 2 new replacements) under very light use to describe as best doesn't bode well for the product or design. The fact the company will be prepared to send a brand new replacement amplifier out including shipping rather than replace a component in the pence which probably has become a known fault is ridiculous. As mentioned thomann can not be worried about the already copied design being copied. Its just the drive for greed and wealth that over rules any degree of rationality.
