Be aware that the tube biasing procedure in the "mycollins.net" link above is for the VT100 MKII. The MKIII has a significantly simpler procedure requiring only 1 meter, and a few minutes of time.
When to replace 6550c on ARC VT 100 III
When should I replace the 6550c on ARC VT-100 III?
The unit is a little over 2yr old and is used often.
Will I hear a change in the quality of sound that indicates tube wear, or do you just wait for them to fail?
Will Fresh tubes sound better even though I don't detected any trouble?
