Default Trident - Three-leg Shunt Regulator

Russ,
any news on the manual for the Trident - Three-leg Shunt Regulator?

I am also a bit concerned about how to make the three Tridents fit on the B2 when one uses the green screw connectors for all connections. Anyone have succeded in doing this and ahve a poto?

The fit on the BII is no problem even when using the terminal block. It's a tight fit but ok. What's worrying you?

not a problem. thought they are designed to fit in the first place?

I was concerned that they would not fit with the terminal blocks in use, but I see now in Coomstech's photo above that the Tridens will fit but it will be a tight fit.

Default My brief experiencing of hifi juice

Finally I had installed these hot looking Trident trio in My BII.

Most noticeable implovement is well controlled and naturally extended bass.

each instrument's attack,decay,echo are now better defined in details.
I think this adds - sometimes slightly more, sometimes much more - emotion and groove into the music.

Drums, Basses are really shines with BII + Trident combo, IMHO.

Now my BII can't live without these tiny gems.
Thanks Brian and Russ!

The resistor in the Trident kit sets the main CCS current in the Trident super shunt regulator as far as I understand.

What curent value is set by the supplied resistors?

Also interesting to know woud be the current draw for the three consumer circuits on the Buffalo2. Does anyone have these currents?

I have a question: if I connect the Trident I don't need the AVCC module, right?

Incorrect. You absolutely need the AVCC shunt regulator.

It is the same topology as the Trident, but both sides share a single Vref so both channels get the same voltage (and output level).

I chose resistors values to give 50-60mA of current headroom for each position. I don't have the total current numbers with me at the moment.

Thank you Brian, so I only have to solder the Trident regs in BII board, or I have I to change something?
