How to Wire Brain Mono Block Kit

[jawbreak]

Hey all again.

Ive been reading and reading brains manual and nuuk site on how to wire this thing and I want to make sure I do it right.

First of: On the boards what do PG, OUT, OG, SG, N, CHG all mean?

Next: I have two transformers and two rectifier boards, I got two of these http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=122-615


Heres the diagram:

2x115V

BLU *--- --- * BLK 0V
| |
GRY --- --- RED 22V / 3.64A
| |
VIO * --- --- * ORA 0V
| |
BRN --- --- YEL 22V / 3.64A


For the primaries I tied The two 115s together and the two 0s.

Since Im doing mono blocks Im confused on how to wire the secondaries to the rectifier and from the rectifier to the amp.
If some would be so kind to explain how to do this Id really appreciate and I understand that asking a lot so thanks in advance.

Well heres a diagram of what I think is how Im suppose to wire it.

Im still wondering what OUT, OG, SG, N, CHG stand for?

In USA so using 115V in

Thanks.

An externally hosted image should be here but it was not working when we last tested it.

The transformer wiring looks fine to me, but you have the colors (polarity) on your RCAs and output jacks reversed and you will also need to tie the AC GND into the Star Ground

OUT = output +
OG = output -
IN = input +
SG = input -
CHG = chassis ground

Let me know if you have any more questions.

jawbreak,

I'll give it a go. This is what I think.

OUT = signal OUT. so should go to red post
OG = signal Out Ground, so should go to black post
SG = Signal Ground, outer connection of RCA
N is really IN = signal IN, centre of RCA
CHG = CHassis Ground

So you probably need to swap SG and IN and also OUT and OG.

Edit: Too slow again.

yeah I was a little confused on what they meant and just looked at pics of finished amps to try and trace where the wires went heh.

thanks guys so much for all the help, tomorrow I finally get to build the cases and put it all together. Hope it works hehe.
