Tubes & Bias 

Power Tubes 

Our high wattage amplifiers are designed around 6L6 tubes - but will 

accept the following tubes & gladly display their tonal characteristics for 

you in your Revv. 

KT88

 – This tube is punchy with a strong low end & a great clarity. The 

extra power out of this tube adds extra headroom & is very tight & 

focused. Overall can be described as “more” of the same sound, with a 

focused attack.

EL34 

– The EL34 tubes are more aggressive than the KT88, they add 

more harmonic content & have a bit more sizzle on the highs. Can impart 

a slightly “British” classic flavor.

6L6GC 

– Our standard, the 6L6GC tube is big, open & articulate.

Note: The tubes listed above are guaranteed to bias correctly & sound 

good in the amplifier, but if you are an experienced technician other 

tubes can be experimented with as well. 6550, KT77, KT66, 5881 can 

be equipped, with care.
