          Yeah, some of those companies will try to get away with anything to save a buck. Normally that's just annoying, but when you get high voltage involved it can be worse than annoying.

            You can fix that with more cowbell.

              I know you want new but a used quality amp is in the same range. Check audiogon or us audiomart. I’ve had great luck on USAM. Something like a used PrimaLuna Prologue with new tubes. The adaptive autobias works so well I bet the original power tubes still work though!

                Cheaper than those tubes.

                  I did, but I didn't see anything I liked. Thanks.

                    I have built 5 tube amps and 3 tube preamps, 4 of those were my own designs, the others were well researched internet DIY designs. My highest wattage tube amp is 35 watts per channel. They all sound great and have virtually no hiss and no hum. That said, in my opinion, reading what speakers you have and what type of music you enjoy, I think your goal of buying a tube amp will end up disappointing you.

                    I never expect any of my tube amps to fulfill what you are expecting. I love them all for modest/medium level listening to a totally different type of music. But when it comes time to crank it with music that has great kick drum and electric bass I hook up my 250 wpc ClassDaudio diy amp or my Adcom GFA545ii. Doesn't mean I don't love tubes.... the big solid state amps just do that application better.

                      .
                      I don't want to sound contradictory to what I said, but I do agree that will likely end up happening, which in a way I'm sort of counting on it. I'll probably relegate it for my office use once my vacation is over and I go back to work in August. I can't really crank it up there so I guess it would be right at home. Perhaps.

                        I started looking at the little Tube Depot tube amp kits and ended up with a Dynakitparts ST-35, and then a Vacuum Tube Audio (tubes4hifi) SP8 preamp. The little ST-35 has very nice transformers according to "experts", widely described as best sounding vintage stock amp. 17 watts/channel. It all sits under my bed now.

                        I'm gung ho on kits, but laying out and parts sourcing a diy effort like pwr ryd has shown here is beyond my skills.

                        I'll sell you the ST-35 if you don't want to build. It's "like new". Really heavy for its size. The preamp would be way over your budget.

                        I don't know how up to date this site is, but lots of info there at least.

                          Why does it sit under your bed if it's that good? 17W seems ....low....lol.

                            There's about 8 amps under there. All good. More in the basement. I can't use them all. I got rid of the big Singularity full range high sensitivity speakers I made to use with that amp. I had a veritable wall of speakers in my living room. I downsized. Looks better to me. It's a hobby, I'll pursue it as I see fit.

                          Vacuum tubes are just plain fun. Designing and building tube amp circuits that actually work is fun. Fabricating the cases and doing the point-to-point is fun. Having a "I did that" show piece is really cool.

                          All that said, there are so many reasons why transistors and now chips have replaced tubes.

                            Craig and TomS held my hands while I built a simple tube preamp. As he said, it is fun, educational, and you can say, I did that.

                              Why do some tube amps have tube rectifiers and others don't?
