amp dies in middle of playing

I have an old adcom amp that occasionally dies whenever i play bass heavy passages at high volume. This is a new problem as the amp used to drive to far higher levels with no problems. The way it happens is ill be playing a rock song at loud but not rediculous volume, like 11 on my preamp and the music will cut off and then come back on after the amp protection circut turns back off. I think its a power supply problem but any suggestions would be greatly appreciated.

Did you buy your pre-amp from the dude in Spinal Tap? I know all his gear went to eleven. Now that's a MOD :^)

Have you changed speakers or speaker cables ? If using a combination that is more reactive, the amps' protection circuitry could kick in sooner. Otherwise, it is not uncommon for circuitry to degrade with age. This is especially true if exposed to higher than normal heat levels and the inside of a power amp qualifies as such. You can probably send it back to Adcom for inspection and repair, as their prices for doing so are typically quite reasonable. Sean

PS... Glen, i think he meant "11 o'clock" : )

I believe that Adcoms have internal thermal protection, it could be that it is just getting too hot. Place it all by itself, NOT in a cabinet or with other stuff stacked on top, and NOT sitting directly on carpet.
