ARC SP-6 Warmup time

I just bought an Audio Research SP-6 preamp. It takes about ten minutes after powering on for the power lamp to stop blinking and the unit to start passing signals. Other than that it sounds perfect on all inputs. Is this at all normal? Does it indicate something is about to fail? Ten minutes to warm up is more than annoying.

Which version of SP-6 do you have? The power LED on the SP-6 and SP-6A don't blink.

Starting from SP-6B ARC introduced a timer circuitry which auto mutes output on power on. If yours is AP-6B and later, I think that is what you are seeing. It is normal. Nothing to worry about.

All the SP-6's sound great. I like the 6A the best.
