I own a OldChen 845-A 300B I bought in Amazon for $1600 and it is fantastic, quiet and no issues so far. I also own a Reisong A12 (a version of the A10), and the same. And also my favorite, the Reisong (Bouyarange or whatever) A50, a 300b tube amp, and more of the same. I tried once a cheaper one, like around $200, with phono and bluetooth, and it was a lot of fun but stopped working in a year or so. I also own a Jadis Black Orchestra and it blew a tube right out of the box, $1000 bucks later sounds very good. I also have an Accuphase E-280, the jewel of the crown. I owned once one of those fantastic Decware that I had to sell because of the hum, probably a problem of my house DC, I don’t know, and I also had to sell a Pass Lab A25, the integrated, because it runs hot, I mean hot, like 50 C. My point is that there is a lot of snobism and even ignorance around Chinese amps. They can be good or bad, like any other amps, but they all have something in common: they are very inexpensive, and if you find one that works well in your system, does not make noise (oh, I forgot had to return the EL34 based Resisong because of the hum too), etc. it could be the bargain of the year simply because they are not wildly overpriced, like most of the hifi gear these days, we all know. And, yes, you can kill yourself if you play with one of these things , Chinese or not, if you have no clue what your are doing.

Picked this up inexpensively to try on my Klipsch Quartets or Chorus 1s. Do not know much about vacuum tubes. I have recapped many ss amps but this is foreign to me. Seeking any and all advice on various nuances.
I have a significant amount of silver coated copper wire encased in PTFE, was considering replacing the wiring. Have not opened it up yet so more to come based on what I find. Thanks for any feedback.
