7 months in with my Art Audio Jota I have noticed that I have to turn the volume knob higher than I used to (very subjective!). I'm not certain, but it has made me wonder when valves need replacing?
The small driver valves have been replaced with NOS recently, but the main 300B XLS had quite a few hours on them and I must have had it on 4-500 hours (I'm a sod for falling asleep listening and waking up at 4am!)
Will they just "pop" or gradually loose power? Any other tell tale signs?
Cheers,
Rich.
