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).
