Specification subject to change without notice.
*RMS watts Do not literally exist! But this figure is based upon the RMS
voltage output (V²/R) to indicate continuous output as opposed to "peak"
output which is mis-leading.
*Triode a simple valve with only 3 elements, this gives very linear
amplification. Some "pentode" (5 element) valves can also be wired to act as
"pseudo" triode valves (not in this amplifier).
