I had a similar experience when I first started with GCs about a year ago.

I built a couple that always seemed to breaking up and distorting, with very low output. After checking, checking and checking again, I was totally bemused, so I finally connected up another driver, and lo, everything was fine. This confused me, as the old driver I then used in another system and it was fine. To cut a long story short, I eventually traced the problem to the length of speaker cable I was using as a test hook up, it had an intermittent internal short:rolleyes:

Moral, check everything, not just the obvious!;)

Thanks Al. I reckon the best solution would be to have a hi-fi mate and do each other's testing. It's like checking your own spelling mistakes when writing, often you just don't see them whereas somebody else comes along and points them out straight away!

I once bought an old Ford transit van with a seized engine. I bought another engine and swapped them over and while I was buying gaskets etc, I bought a set of new spark plugs.

But try as I might, I could not get that engine running. I stripped it down several times, checked everything in sight but after a couple of months, and a couple of experienced mechanics taking a look still it would not run.

Then one day, hearing my cursing, an elderly neighbour came over and suggested starting at the beginning and checking the spark plugs. I told him that they were all brand new, but he insisted on putting in the old ones and, you guessed it, the engine started first turn of the key! :(

I'm very glad to report that the little GC monoblocks are now singing again. For the record, the one with the new chip/coupling caps came into full flow after about 20 minutes. It was quite noticable!

And I'm pretty sure now that the chip that I took out is OK so I'm halfway to another GC :devilr:
