Old Style DCB1 information

The basics on the boards....
The hypnotize is a 1 input/1 output Shunt regulated Direct Coupled Pass like B1 buffer. It has a relay delayed startup to avoid DC problems for the amps. This board (and even Mez) can be used just as a shunt power supply, and their is a thread for this also.

The Mesmerize can use up to 6 muting relay inputs, and is a larger board. All others matters being equal.

Here are some relevant threads.



Attached is a semi-built DCB1 mesmerize. Also the main schematics of the device, in case you need to troubleshoot. The below shot is a bare Hynotize PCB.

    I have some sets of takman's without the 220k resistors. They can be had for 3.50 with a board.

    I hope to get some 1/2 220k on a next exotic parts order.
