Hey there,
A few questions about tube life & my LD MK III amp:
- any idea on the length of the power tubes' life? (The previous owner said they'd put about 200-250hrs on them, I've probably put about another 120hrs, at least)
- what about driver tube life? I'm using a pair of Mullard M8161s and have put about 60 or so hours on them
- also, if the amp is left on, but with no music being played ('phones still connected), does that wear out the tubes equal to when there's music being pumped through?
-what type of power tubes can I use to replace the stock ones?
- the reason I'm asking these questions is the sound of my Little Dot MK III seems to have thinned out and become a little harsh, less warm & cozy and less deep bass - is this due to the tubes wearing out, if so, which ones (ie power or driver?)
Any help or info anyone can offer would be greatly appreciated.
Thank you!
