Yes, this should always be the protocol...no matter how well designed your commercial/diy gear may be.

Have you sequenced turn on/off? Or tried turning it on w/volume at zero?
Turning it on with volume down makes no difference.
I normally do follow the same sequence but thought wanted to be sure. Don't want to blow my Tannoys. using the wall swith on the SMPS is the best as the power comes on slowly.

Thanks,

Kffern

And is standard protocol with separates in any event. As has been stated 2 or three times. Why would anyone purposefully turn off or on a pre amp with the power amp already powered up anyway?
Good practice would be not to fool with any thing upstream while the power amp is on. Turning it off first keeps various transients at shut down of upstream components from being amplified and sent to the speakers.

Here is my progress so far. Just resistors, jfets and some caps. I wanted to wait on getting the enclosure before running any of the wires for everything else. The picture is not the best so I apologize about that.

Nice B1. I'm a little curious about the output wiring...it looks like it is split into 2 sets of connectors but I could be wrong. Would you mind explaining???

Thanks,

I ran 2 more outputs parallel off first set RCA outs.
for Subs, It works great.no drop in volume at all.
Mr Pass told me this would work,and it does perfectly.

The pic is posted at above 2573.
It is very simple just come off of your existing output RCA
jacks.solder a wire from ground to ground on another RCA.
then simply solder a wire from center pin to center pin .
all you are doing is wiring 2 more RCA parallel off existing Jacks.
just look close at the picture the smallest wire is feeding
the Sub outputs.
