Buy tubes from Audio Research or not

Just a couple of comments about retubing a Mkiii. It uses 6H30 tubes not 6922's. The 6H30's don't need to be adjusted like the 6922's from the Mki and Mkii's, you only need to bias the 6550's. If you have a multimeter and the Audio Research bias tool(looks like a screwdriver with a small blade and wooden handle) its a straight forward process. Although i install my own tubes and bias my VT100 Mkiii, I still buy my tubes from ARC. They are more expensive but if a tube fails, Arc has a 90 day warranty period and would cover appropriate repairs. Its just a risk decision on how much you trust your local Tech or yourself.

Boneman thanks for the clarification Mklll.

You might ask how much to bias your tubes, two matched quads from Tube Store or Tube Depot. Tube Depot marks each tube in the quad with it's value.

He's getting the tubes from the actual Importer. They are going to match the tubes for him. Then he will install and bias them. He has retubed ARC gear in the past so I believe he knows what he is doing.

Samhar...what tube tester do you use in your set up? Are there any current suppliers of tube testing equipment or does one have to buy an old used unit?
