Where is the original Mezmerize thread? I see threads on building one but none that seem to be the original design thread.
The Mez and the Hyp are simply DCB1.
The Hyp has one relay for muting the output. But it needs an alteration to get low hum in many system configurations.
The Mez has the same muting relay needing the same alteration and an extra 6 relays to select alternative inputs. Again the 6 relays can be rewired to minimise noise and hum.

*The output relays are shorting to earth at standby or off mode in all later PCBs for a long time now.
