Question issue with fatman iTunes mk2


Novice Member
i have a fatman iTunes mk2 valve amp with fresh tubes, very quiet & sounds great but after 20-25mins, the sound degrades!!! sounded fuzzy. had to switch off but when you return a bit later & start again, its sounded good but again after some time, the harmonics just become 'fuzzy'
any idea what the issue might be??

Sounds like you need to get it repaired (likely defective "fresh" valve, but might be something else) [and I also guess you mean Fatman iTube MK2]. The manufacturer will be able to sort it out.
