So I am going to write some details down about the DCB1 Hynotize Hot-Rod buffer. The current production board is black, 2 oz copper and 2mm thickness. (See below) The below blue pictures are prototype boards and are not representative of the product.

Here are some of the specifics to help understand ordering parts for it etc. This is not a detailed build guide, but there is a link to one below from another forum member.

They can handle 10mm pitch snap-in capacitors 25mm width capacitors.

There are positions for smaller MUR120 type diodes OR MUR820 style TO-220 style diodes. Not both!

The vRef LEDS can now be bypassed with a 25mm Film cap or a 100uf electrolytic. The film cap by consensus is best at .22uf.

The CCS resistor is now about a 28mm pitch, and can easily handle most 5 watt wirewound type of resistors.

Here is a build guide another member did.
It is excellent, and on audiocircle. Thanks Wushiliu

And here is another article about the Hot-Rod DCB1 written by Corpius.

Here is a example of a balanced setup that works. Special thanks to johnwmclean and nycavsr2000 for this work.

Regarding grounding of the balanced project.

FYI the signal return on both boards are connected to ground chassis via a ground loop breaker as follows;

The ground loop breaker is a 10Ω 5W resistor in parallel with a 0.1F capacitor rated at least 250VAC. For safety this capacitor should be rated for class X or Y (good for across-the-line use) with flame retardant casing.

Just so you truly believe, here is the real deal.

Nice casework, huh?
