Do chinese tube preamp/amp clones interest you?

I've bought a Chinese Tube amplifier about nine years ago that is still my preferred every day amp. But when I received it and plugged it in, the sound was dark and totally closed in. Fortunately, I found an upgrade on a DIY forum for that exact amplifier. Music Angel 845 Class A amplifier upgrade.  After a total circuit remake and installation of top quality audio parts, this thing sings to it's hart content.  Of course, you have to know your way around electronics, and you have to make sure to not get electrocuted. This thing packs roughly 1000 volts. I would not recommend it for the novice. For me, it was much cheaper to buy the amp and redo the circuit than building from scratch. Not to mention of a better finish.  I also had to change all the tubes with NOS, as they where poor quality sounding. But super quiet. The only repair I had to make was to change the turn on relay after two years. Hopping this information will help.
