Service And Repair - Decware SE84C+ Owner's Manual

DECWARE OWNERS MANUAL – MODEL SE84C+
rotated. If the Q-Tip comes out with dark stains on it, your jacks were dirty. Jacks can
get dirty after only a single insertion of a non-cleaned interconnect cable. Having clean
connections is important. Finger oils do not help the sound.
Products like Caig DeOxit, ProGold and other contact cleaners/enhancers can also be
used as a part of a regular maintenance program. The volume control should not need
cleaning as the chassis for this amp is sealed to keep dust and smoke out of the inside of
the amplifier.
The amp is self-biasing so there is no maintenance or adjustments to make after you
install new tubes.
POWER CORDS and CONDITIONING
Upgraded power cords can and do make a difference when the overall strength of the
audio chain begins to show a sock power cord as the weak link. We hear nice
improvements with the use of silver/Teflon DHC-1 power cords.
TWEAKS
The biggest thing regarding tweaking the amplifier itself is going to be tubes. Every tube
will sound a bit different. Rolling tubes, in particular the input tube, with your favorite
NOS (New Old Stock) can yield some very synergistic effects. Beyond tubes, a good
power cord and clean power, the only thing left is vibration control. This amp will suffer
from vibration less than most due to the heavy steel it's built from. Things like tube
dampers and high mass stands can further improve focus.

SERVICE and REPAIR

Your amp is covered parts and labor for the lifetime of the original owner. Should it ever
need repair or you just want it checked, contact us or fill out the RA form on our web site
and include it with your amp when you ship. We'll contact you after it has arrived and let
you know what we've found and determine exactly what caused it. So far less than 1%
of Zen amps have required service since the amps were launched in 1998.
