Mackie M1400 poweramp problem

I wouldn't expect it to work for very long. Seems to me that you have a problem with anything made in China. Not at all but the quality varies dramatically. I'm expecting to be going to Shanghai / Ningbo quite soon in fact. You might also remember some time ago when I posted for help with a dead Studiomaster 700D. The fault turned out to be a bad power transformer which was not economical to replace even by substitution with off the shelf parts. Only because our Indian sub-contractor had bankrupted the company. Those transformers were custom made by Toroid International which is a highly respected brand. I'm sorry you had that problem but it wasn't a design oversight for sure. Ah ... Studiomaster. I will remember that Graham, when I next get one in that's giving me some grief ... d;~} Stop for a second to think how many tens of thousands were made and how few you see. I just bought a 700D on ebay btw for a club install that's going 3 way active (for the HF drivers). You can see I do have confidence in my own products. And you can always email me for repair tips. Graham Yes, I don't see that many. But always useful to have a 'contact' within a company ... Arfa |
