Output Tube Warning; Other Output Tube Information; Tube Life - Decware SE84TS TABOO Owner's Manual

OUTPUT TUBE WARNING

The SE84TS is designed to use either EL84
output tubes or SV83 output tubes. No adjust-
ments are needed when switching from one to
the other. Of the type SV83 tubes carrying the
Svetlana name there is one batch known to be
questionable and ARE NOT RECOMMENDED for
use in this amplifier.
The tube on the left is an acceptable SV83
output tube for use in this amplifier. The tube
on the right with the smaller logo is NOT accept-
able for use in this amplifier or any Decware
amplifier.

OTHER OUTPUT TUBE INFORMATION

While this amp can use SV83's we recom-
mend the milspec version of the SV83
called the 6P15P-EV. In this amp, these
tubes give a slightly warmer presentation.
Since the SE84TS was primarily designed
for an EL84 output tube, you will find the
amp to have more spank, more presence
and a bit more power when using them.

TUBE LIFE

Output tube life is rated at either 3000 or
5000 hours depending on the type tube
used.
Rectifier tubes can easily last the life of
the amplifier.
Input tubes will vary from tube to tube
and should be checked yearly.
The easiest way to check input or output
tubes is to replace them with a known
new set and compare both sound quality
and power output of the amplifier. If you
hear very little difference, the tubes are
still good.
