Bill Perkins of Pearl HiFi in Calgary (link below) cryo treats pre and power tubes. He tests them afterwards and grades and matches them. He is very experienced at doing this and I believe all dealers use him. I believe he does them in batches and is open to people sending him a bunch whenever he is ready to do a batch.I have no commercial interest and am merely someone who formerly paid a dealer a great deal for Bill's treated tubes and loved them. I have since sent him a bunch of pre-amp tubes, and will later send him some 30Bs. Be patient, it takes a while for Bill to catch up with his mail. It took many years for me to find Bill.
