After cranking up my Blackstar HT-20mkII to full volume, it started making crackling and oscilliation noises.
Our (me and my friends, plus an amp techs) guess, is that one or both of the power tubes failed.
The power tubes look burnt , like there is soot stains on the inside of the glass. So, I decided to order some replacement ones once I got my christmas paycheck bonus.
... there were three kinds of tubes for sale here in Norway,
EH, Mullard and TAD. The amp came stock with TAD tubes,
, I've heard bad things about EH tubes (which were the cheapest),
The TAD's were too expensive, so I ordered two unmatched Mullards.
I'm going to put them in when they arrive, and also reduce the bias a bit.
I really hope this will put the amp back into working order...
(OFF TOPIC)
.....
I also ordered a low-ohm, high sensitivity , and cheap AKG headset. As my expensive Beyer-Dynamic isn't loud enough with anything but professional studio/Hifi equipment.
Cost me over 150USD in total! :o ... norwegian gear prices are crazy.
(So I hope my family and friends give me money as christmas presents this year, lol)
