I've heard so much about this Pre when it's modded, that I'm looking for one to modify. Can anyone who owns one, or has owned one shed some light on this Preamplifier.

Thank you.

I have had my PV12L extensively modified by Bob Backert of RHB Dezigns.  He focused on the power supply section of the line stage, bypassed the circuit board  traces with gold coated silver wire and added bypass boards to improve the performance. It is still a cj at heart but is more open sounding with a tighter more responsive bass response.

@orpheus10  I have experience with Musical Design and agree that you might visit them, especially if they are in close proximity.  But first...finding that PV-12.
@unclekenny   Congratulations!  Bob and his son are real craftsmen.  I too live in close proximity to the Backerts and have had very extensive mods. done to my cj PV-12L.  It is truly remarkable what they can do, especially with the power supply, to improve the stability and performance of the gear they modify.  The cherry on top is that the Backert's are salt of the Earth folks who truly care about their customer's satisfaction. 

I hope you enjoy your Backert Labs cj for years to come.
