RWD, you don't need to spend $1,000 for good NOS tubes for your Rhea, and all of the 12ax7 tubes don't have to be as low noise as the V1 and V2 positions, which are the most critical.
Another option would be selected modern tubes from Aesthetix or Jim McShane, although Jim has a waiting list for a Rhea tube set right now.
Best Regards,
