Nagra VPS issue


Hey all, just installed a secondary Nagra MC input card in my VPS.  Have the Loading card, ground, ribbon cable and everything all hooked up.  It was very simple.  after the unit warms up on mute I get a normal, solid blue light.  When I switch to input A, original input, remains blue.  When I switch to input B, I get a rapid flashing blue LED indicator.  Not sure if there’s an additional jumper or something I need to flip on the board if I am running two cards.  Anyway, if there are any Nagra folks out there, I’m all ears.  Was looking forward to running a new cart tonight and doing some comparisons.  I’m sure the dealer will get back to me with my inquiry, just thought I’d post up to the community.  Thanks!

It was a simple jumper move from position A to position B.  It wasn't called out in the owners manual. The unit sounds oh so fantastic, super quiet, like dead quiet.  If you didn't know better, you'd think it was solid state.  I have been rolling some tubes 12AX7/12AT7 using some early 50s Telefunken and Amperex.  it responds very well to tube changes.  I think i prefer the Amperex, it's a nice in-between the clean Telefunken, and the oh so lush Mullards.  I haven't tried the Mullards yet, but no rush, just enjoying the unit.  

 

I purchased the unit from David Michael Audio, worked with David, he was extremely responsive and had a great purchase and support experience from him.  I'd for sure go back to him!
