I have been searching the web but didn't find any proper answer to my question.
I baught my Mk3 around 2004/5 (love it) and got a mk1 today.
I just tried the mk1 and got very surprised by the very different voicing but also by this impression of lack of power.
I was so surprised that i used a sound meter to mesure both amps and i gave me the same result of 90 db !
So it apparently as to do with their different voicing, mk1 staying cleanner and brighter.
To be able to approach the same sound i had to set the amp i an opposite way :
- 6 on master and 3 on gain for the mk3
- full master and 6 on gain for the mk1
![Shocked :shock:](./images/smilies/icon_eek.gif)
Is that a normal setting for the mk1 ? (maybe as to see with a strange power tube selection, having two 6550 and two kt88, wich i plan to change for 4 6550) or do you think there is a problem with tubes or caps ?
