Wiring check please!

Here is my first attempt at wiring the briangt 3875, one 330va avel landsberg transformer, one rectifier board, 2 amp boards.

4 amp slow blow fuse on ac hot.

Is this all correct so far?

Next, do I go from rectifeir board as follows:
V+ to fuse then to V+ on both amp boards?
V- to fuse then to V- on both amp boards?

CHG on each amp board to star ground?

I'm no expert but I don't think any fuses after the rectifier board are needed. As far as the star/chassis ground I have yet to have to use any chassis grounding in the 3 Briangt amps I have built. I'd pay close attention to wiring and try it with out it first.

Hi,
is that back insulated cord to the bolt connected to the chassis?

I hope it is only the safety ground (earth).

I do not recommend you connect your audio grounds to chassis.

Your secondary fuses are less common but still worth having. Try a rating of about half the peak current into your lowest load.
i.e. Vpk = 28V and Rload=4r then Ipk = 7Apk. Use a F3.1A or F4A
8ohms speakers F1.6A or F2A.

Caution:- what happens to the amp output if only the +ve or -ve fuse is removed/blown?

Yes, the black (really dark green) wire goes from the ground of line cord to the chassis star ground. Am planning to also connect the CHG (chassis ground) point from each amp to this star ground as well.

I do not understand why you say to not do this as it seems to be what the briangt design calls for.

CONFUSED!

If I do fuse each of the sets of leads form rectifeir to amp boards, what exactly is the downside? What are others doing?
