Ah, got it. Thanks for the terminal block recommendation.
Yeah, he hasn't said anything about grounding. He is supposing that you will tie it to the metal chassis.Hi James.
No, I meant to wire everything to the terminal block. One of those big plastic things with about 6-8 screws in it.
Then attach the terminal block (plastic) to the chassis.

ok, so that I'm on the same page. Line and Neutral go to terminal block and earth grounded to chassis, or are all three tied to the terminal bloc?...
Either way. You can create a star ground on the terminal block if you like or you can do that on the chassis but you should at some point ground the chassis in case it gets shorted to a live line which would then potentially electrocute you if the chassis were not grounded.

gotcha. thanks
a "control" transformer could be one that only powers the ON OFF relays, power to protection and delay circuits, illumination, in fact anything that is not direct audio amplifier.
Live and Neutral to your screw fixing and onward.ok, so that I'm on the same page. Line and Neutral go to terminal block and earth grounded to chassis, or are all three tied to the terminal bloc?...
Protective Earth wire direct to chassis Safety Earth.
Then you can connect anywhere on the chassis to the Main Audio Ground.

So I've powered up the DCB1. I'm getting -5.3mv right channel, .6mv left channel. I take it that's something's probably not right...
and do I jumper BOTH 600Rs or just the one that says Note? (I have a 12v relay)

What are you asking?

Sorry, they were unrelated.

Great, I went and fired it up anway connected to sources, amp, etc. Good clean audio. So far so good!
Have you done any mod yet?
No, no mods yet. I read something about hot-rodding but am not totally sure what entails (enough info as it is to process in the two threads). What mods would you recommend?

With just a couple of hours of listening done, this is an exquisite upgrade to the standard B1. Congrats to the designers.
wushuliu, do what tea-bag sais. Let the circuit burn in properly, get used to its sound and enjoy it. After some hundred hours, perform the mods so it will be easier for you to notice some changes.
Just for scientifical purposes 😀

No, I have no intention of modding with this board anytime soon, if anything I have another hypno and 2 mez boards that I can work on (prob the mez as I have multiple inputs).
No doubt, the performance of this design is euphoric. It's like going from really great well-produced cd to SACD version of that cd. Overall characteristics are similar to standard B1, but articulation and resolution bar is raised.
'Money' from DSOTM just gave me goosebumps...
