amp wont turn on?

Gelmhirst:

What a relief, so the amp is OK.

Just to confirm, you use the original power cord in the usual wall outlet and it works fine, right?

If so is the upgraded cord a new one? Did you buy it used?

I bought the AZ pwr cbl used, the factory cbl is plugged directly into the wall...AND now it does not pwr up again, same scenerio....

I had the same problem when I had a Cardas power chord soldered into my Adcom 555. The guy who did it was stifled and had a friend who was a tech in the area come over and look at it. Anyway i had to leave it there but when I arrived home there was a message on my answering machine telling me that the standard Adcom fuse could not handle the current when powered up so they put a bigger fuse in and everything worked then. I hope this helps. I have had no problems with it. Call Bryston and ask what size fuse bigger than the one in there could you replace it with and then fire it up.

Hmm, my SST has no fuse, I'm almost thinking the fuse in my fuse panel is not enough for the particular circuit my amp is on...although the 3BST seems to work fine....

replacing a fuse that blows regularly with one with a higher rating is really dangerous. There is a reason a fuse keeps blowing.
