One dedicated breaker, #10x4 line, one leg to a dedicated 9’ copper earth ground stake and the other end to the amp chassis.
Both amps to the same receptacle. Use a hospital grade 20 amp receptacle. They are sturdier.
One dedicated circuit for each mono block?
If I have a dedicated 20 amp Circuit is that ok for two monoblocs? I read that a separate dedicated line is better for each amplifier. So the outlet can't have two plugs but it's better to not use one of the two plugs when connecting a mono block?
I have a transparent Power isolator which I know use to plug amps into.
So maybe a dedicated circuit can be used to plug amps directly into and then have Power isolator connected to a separate Circuit for everything else.
I am trying to evaluate the merits and to need for getting a second dedicated line while installing the first.

Cashflow is of course a relative thing but, looking at the cost of big Class A amps new today, the KRS200s are great value. There is a fairly ready supply at between £6k - £12k. They are nearly 35 years old now so expect service issues. I bought mine in the early 90s from a Krell dealer ex-dem. I paid £7.5k then. About 12 years ago I had them checked over, serviced and fully re-capped. That cost £3.5k then. But for £12k today expect them serviced and re-capped. I reckon that's value and they sound great against today's big designs, many of which have been toned down for the green lobby and don't run in pure Class A right up to the top. And don't they look the business!! |
@ditusa you have given me something else to ruminate & worry about. I own a house built in the ’60s and when I bought it it did have the old style fuse box and there is one circuit with a few outlets WITHOUT the 3rd wire (ground). Is there a good chance there is some knob & spool going on here, and would I be able to see that by pulling one of those outlets and would I be able to identify it from what wire I could see from the removed outlet? |
Hopefully that dedicated 9' copper earth ground stake is tied to the other load center ground rod(s). Ground rods only exist for lightning protection, and you should never have any that are not tied or connected to each other. |
