thanks Brian and carlosfm,the amp has completed.
my gf said the inner connections looks really mess but its sound cool we are hearing now.
dc offset,Rch=-38mv,Lch=-36mv.it is totally quite without signal input,and no pop sound when turn on.I will test bridge later.

carlosfm said:Cat5 cable for PSU?
What's the problem with that Carlos? i mean if you run enough lengths to obtain high guage? (i was thinking doubling what digi01 has now)
BrianGT said:Looks good. Where do you get the power for the DRV134 board?
The middle PCB (DRV134?) doesn't look like its connected to anything, including any signal input or output.
as by digi's thread on the drv134. It has voltage regs on board and gets it power from the trafo.

thank you Evilsizer,the url put across mine ideas. the design has another set up-HDAM,you can pile up series boards,they could powered through C3,C4 on the upper board.

I have not connect the drv134 in the unit,I will try it later.

Yes,I use cat5 cable.I like simple way,even without solder.

digi01 said:hi friend Evilsizer,you are welcomed
I wonder has anyone completed the drv134 module?
Zang
err not yet digi i just have a music only system in the works and could use some more of your boards for this new setup ... still have any or any chance if we have enough interest we can do another groupbuy?

YEAH!I see
P.S.
your hand maked connector looks really nice.
Evilsizer said:well im slowly building them now digi... my music only system is going to be BR-100's x4 @24volts regulated. If i did my math right i should be around 100-110 watts rms @8ohms. If i use a 500va trans should i look into a current limiter?
are you going to ues my regulator pcb?if thus,you can beside the current limiter.
Evilsizer said:also forgot to ask what is the regulator set to for voltage output... i keep going over stuff but i cant seem to figure it out...
you can adjust the 2.2k resistor for expectant output voltage(from 3VDC to 35VDC,basis on the transformer supply voltage).
