I finally got it squared away today. It took three trips to WW Grainger
before I had the 120 volt DPST relay in my hot little hand. I stopped at Home Depot on the way home and bought a blue plastic work box along with an AC outlet and a face plate. I actually soldered the spade lugs onto the wires (scavenged from the garage)and stuffed everything into the box. It makes quite a neat package with the two cords coming through a grommeted 1/2" hole in the back of the box. I plugged the high powered amp into one side of the outlet and the CD player into the other. I plugged the relayed plug directly into the wall and the cord to the coil into the back of the receiver. Et voila! It works perfectly. Now I turn on the receiver and everything turns on at the same time. I should have done this long ago. Thanks to everyone who contributed ideas to the thread. This is the relay I ended up using: http://www.grainger.com/Grainger/items/1EJH4 Mortimer Schnerd, RN mschnerd at carolina.rr.com |

Audiophile equipment should be powered up in sequence from input-source devices first (cd, phono, tuner) to power amps last, and powered down power amps first then input-source devices last. So pusing on would trigger the relays to go on in sequence (at 5 second intervals) and pushing off would trigger to relays to go off in reverse sequence. |

My external power amplifier is a Dynaco 400 and it already includes delayed turn-on to prevent speaker thumps. I've had this since 1974 and it still sounds great. http://home.indy.net/~gregdunn/dynac...400/index.html As for powering down, I don't see any particular downside to simultaneous shut down.
