Perhaps someone could be good enough to comment on the whole Gerber File business.Recalling my efforts to have ZenV4 boards made ,the board maker kept coming back seeking additional files which confused me .The boards never were made . Can anyone throw lite on what to do with these files as well as what programs are required to read them???

Use Pentalogix Viewmate. Free gerber viewer.

Here is a picture of my unfinished B1 buit in a wooden cigar box. I still need to add the DPDT switch, DC jack and wiring. The 25K stepped ladder attenuators are off of ebay from 8Audio.

I am grounding the chassis with bronze nuts, bolts and washers to copper tape visible on the edges of the PCB. Does this make sense?

Can someone explain how to hook up the six poles of the DPDT switch to the six connections on the Pass-DIY PCB? I know this is probably obvious to everyone else, but it is not clear to me.

Here is a close up of my B1. I hope to complete this soon. It has been slow going for me. Any suggestions?

If you go to the ebay page you bought the pots from, or any other 8audio potentiometer page you will find a link to a picture of how to hook it up. After that pic its not to hard. Be careful. I bought 2 stereo pots from him and waited a very long time to use either. Longer than I felt was fair to ask for a refund. The build is nice and the resistors I am sure are of decent quality, but the stepping is messed up on both pots. I get a few areas where volume takes a dive where it should have increased.
