Rockford Fosgate Signature Phono Pre needs repair

Hi guys, 

Hoping someone here could point me in the direction of a tech that could repair my phono pre.  I recently moved and despite my best efforts, my phono pre arrived at its new home with a dead right channel.  I have tried all the input switching and tube swapping, but the right channel remains dead.  Any suggestions greatly appreciated. 


The Fosgate phono-stage and headphone amp are long discontinued. The Fozgometer is still a current product and was upgraded to a v2 not so long ago.

Jim Fosgate died this past December.
