Product specifications are subject to change without notice.
Tube life span depends upon things such as amplifier load and
playing style. Power amplifier output tubes have a shorter life
span than pre-amplifier tubes and usually need attention first.
A simple way to check if your tubes are noticeably worn, is to
replace them with a spare new set and listen for any
improvement in tone quality:
A LWAYS unplug the amplifier when replacing tubes.
Replace tubes ONLY with the proper type (see
“Specifications” below).
CAUTION: let tubes cool before handling, they get HOT...
1. Replace the OUTPUT tubes (V9, V11 in FIG. A) with a new
set. Set BIAS and BALANCE. Listen for any improvement.
2. Keep the new OUTPUT tubes in place. Replace the PRE-
AMPLIFIER tubes (V1, V2, V3, V4, V5, V6, V7, V8 in FIG. A)
with a new set. Listen for improvement.
3. Keep the new PRE-AMPLIFIER tubes in place. Put the
original OUTPUT tubes back in the amplifier. Set BIAS and
BALANCE. Listen for any improvement.
If there is a noticeable improvement in sound quality after any
of the 3 steps above, keep the tube arrangement that sounds
the best. Obtain new spare tubes for future testing and tube
replacement.
