  *Dear ppafsn,*

  Hi! I am really interested in buying a matched set. Can you tell me what the
  percentage of running resistance is on the tubes? Also, have you checked the
  elements with a microscope to identify any marsentite at the connection
  joints. Real collectors would want to know if the tubes can run in a
  push-pull configuration to minimize the total harmonic distortion of the
  amplifier.

  *I am awaiting his professional opinion, so valuable when making that
  purchasing decision.*
