Amp and preamp on same outlet?

Thanks, Jim. All good points.

I would like you to also give an example where the branch circuit wiring is #14 gauge wire which would be a more real world example for the majority of homes in the US where guys are plugging their audio systems into a 15 amp convenience outlet circuit in the living room or a den.

The resistance of 100 feet of 14 gauge wire, corresponding to a 50 foot run, is about 0.25 ohms. For the 30 amp current spike I hypothesized, that would result in a voltage drop of 0.25 x 30 = 7.5 volts. A 75 foot run would increase that by 50%, to 11.25 volts.

As you indicated, less than optimal connections could worsen that significantly.

Best regards,

Al,

Thanks for your response to my previous post.

Mitch2,That is funny!, my amp got way to hot on just a single pole 20 amp breaker, krell told me that my amp was designed to run on single pole 30 amp breaker, guess what, I did what krell told me to do, my amp has incredible dynamic's, bigger sound stage and transparency, and now for the kicker, the amp never run's hot and operates smoother, my krell kick's a 20 amp in the Axx!

Thankyou Almarg for clearing thing's up for me, A very good job indeed, yes, I have to go about thing's different with my amp, also, a couple of good friend's here on audiogon confirmed what krell told me, why?, they own the Krell 750mcx mono block's, these guy's talk to me often to help me, they have even bigger than my amp, the 750mcx has the exact power supply as my amp, however, the mcx amps have two!, oem to oem, the 750mcx has a bigger sound stage, but with my modds,up-graded none oem caps through out, tweaked power supply, up-graded most transistor's to higher grade,etc... it should be awful close, cheers.

hello,

As per my manual:

A.C. POWER CONNECTIONS: It is important that the HD220 be connected via its supplied 20 amp IEC 12-gauge power cord to a secure, dedicated A.C. power receptacle. Never connect to convenience power receptacles on other equipment. Only use the power switch on the front of the HD220 for On/Off control of the amplifier, or the 12V start- up trigger for remote installations.
The AC power source for the HD220 amplifier should be capable of supplying 10 amperes for 100 or 120 volt units, or 5 amperes for 220 or 240 volt units.
For the very best performance on domestic 100 or 120 volt circuits, the HD220 should be connected to its own AC power circuit branch, protected by a 15 amp breaker. The preamplifier and other audio equipment should be connected to a different power circuit and breaker.

I have been not been up to date on this thread, because I've been enjoying the music too much! This statement is found in other models in the ARC range.

Cheers
