Some months ago I purchased a Little MKIVse from the classifieds here. I love the sound of the amp, the price/performance ratio is for my ears terrrific.
When I first got the amp, a crackling/hissing appeared in a short time in the right channel. Got on the Little Dot website. Was advised by David from Little Dot that I could send it back, they would transfer warranty coverage and fix it for me.
This was evidently an earlier MKIVse which needed a redesigned circuit board to fix varying voltages from the power tubes.
Got the amp back, settled in to listen. A week or two later it started to crackle again. This time I reversed position of the power tubes and it appeared that I had a bad power tube (6H30PI). Ordered a pair of Sovteks and installed. In a short time, the amp started to crackle again, I reversed the power tubes again and thought I must have gotten a bad tube. So I just bought another one and the crackling might have improved, but is still there.
Maybe I am slow to catch on as to what the real problem is. Should I just ditch this amp? I DON'T want to spend another $100+ to ship it back to China for another fix.
Thanks for any help.
