VAC Renaissance Pre-amp owners - Help

Just got my VAC Renaissance Signature MK II back from VAC. Have it all hooked up but no sound from any on the inputs including the phono. I ruled out the interconnects and the amplifier. Has to be something stupid like a switch. I'm using all RCAs and all the switches are set to SE. The output has two sets and I tried using both but nothing.

All the light are on. Any suggestions would be appreciated.

Thank you.
Maybe check to see if any of the pins have backed out in the umbilical connector.
Found out that it's the switch that got installed. Something is wrong and it only works in one setting and not on the 8416 setting. Also, left and right channel are unbalanced - at the lowest volume setting the left channel is silent and out of the right channel you can clearly hear music.
Do you mean the switch between 8416 or 6922/e88cc/7308?

Mine is set to 6922/e88cc/7308 ... rolling NOS Amperex 7308. When I need a change, I roll the stock Golden Dragon e88cc ... cheaper than changing preamps :-):-) Both are excellent but very different sound.
Yes-the switch doesn't work in the 8416 stage. It only works in the 6922/7308 but I have 8416 tubes in the sockets. Is your pre-amp louder in one channel than the other?
That sucks, so I suppose the unit has to go back?

Off that subject I still have not switched between those two tube configurations but reading your replies and Knghifi it appears that your pres were set opposite when received. Are they normally sent out set in a specific? and if so what is that?

Question to any owners, curious what have you found the sonic differences to be when you switch from between 8416 or 6922/e88cc/7308.
