Tube Audio Hints & Tips

• Try to have a soft work area in case you drop the tube.
• Use cloth glove or baggie to hold the tubes, wipe off any fingerprints on glass portion of tube with a soft cloth. Fingerprints can lead to premature tube failure
• Try not put excess force on the glass of the tube this can (rarely) cause the seal between the glass and base to leak the vacuum.
• Do not leave Trends PA-10.1D unattended for long lengths of time during the 22 hour initial burn-in
• The sound of Trends PA-10.1D will open up after about 5 minutes of warm-up. At least half an hour of warm-up, if you are doing some audiophile listening
• Always wait at least 5 minutes prior to turning Trends PA-10.1D back on after turning it off.

Notice:

- PA-10.1D SE and PA-10.1D GE use the same body.
- PA-10.1D SE and PA-10.1D GE use the same body.
- Only use supplied power supply or Trends PW-10 Power Supply Unit.
