I've seen threads where people ask about leaving amps without triggers on, how much do you think it costs? I've got some amps I'd like to leave on, my Sherwood Newcastle AM-9080 has a proprietary on/off mechanism (my only real gripe with it), so I usually just leave it on all the time. It's in a closet so I don't want to have to turn it on a lot. Also, I have an old circa 1983 JVC receiver that I use to power in-ceiling speakers elsewhere in my house. I'd like to leave that on 24/7. Lastly, I've got an old late 60s Crown DC300A that I'm planning on using for my yet-to-be-constructed Infinite Baffle subwoofer. How much will it cost me per month to leave these on all the time do you think? A lot? I'm a bit worried about the 300A, it's a 5 rack space monster from 1968 I think. It has the most massive transformer I've ever seen and the caps gargantuan! I also just got a Harman Kardon PA2000 for my rear centers, and it's switched on my Outlaw 950. It gets warm even when it's on standby. ???
