Replacement Tubes for ARC Reference 6

I realize that the tube replacement for ARC's Ref 6 are good quality, and when I get these from ARC they would be matched.  I believe these are all Russian--good, but not great.  Is there any reason to check for better quality tubes when I do a replacement?  These are 6H30P and 6550WE tubes.

Order a new set of 6H30P's directly from a Russian vendor. Same for a 6550. No need for any special "selection" as ARC claims!

+1, noromance.

The very least you should go for SVETLANA Winged "C" 6550C rectifier. This alone would be an improvement over WE6550. The Reflector 6H30n-DP are the best variants of 6H30p but hard to find and expensive.

I had these tubes in my Ref 6 and heard immediate uptick in overall SQ.

Look for ones made before factory burned down.  Ones made later is different and not very good.

The NOS TungSol ( Harrison NJ ) 6550 is killer in the Ref5se, Andy at Vintage Tube services is good source.
