Affordable US Made Tube Pre/Power or Integrated Options


I'm considering switching to tube amplification from solid state. I'm fine with separate pre/power or an integrated. I'll be driving Enzo XL's in a smallish room (17x14) and listening levels are almost always <90db so 30-40 watts should be more than enough. My budget is fairly modest, $2-3k all in. I don't need phono or more than 3 inputs but I would like remote for volume at minimum. Quality build and sound is a priority as is ease of support/repairs if needed. The one unique requirement is that my preference would be for US made if at all possible. Obviously, this limits the options quite a bit but I'd like to see if I can make it work. If not, I'm willing to look at other options.

Here's what I've found so far

Preamps:
Mapletree Line 2CRM, $800 (not US but close)
LTA MZ2- $1595

Power Amps:
Tubes4hifi ST70-35w, $1300
Audio by Van Alstine Ultravalve-35w?, $1599
Quicksilver Mid Mono-40w each, $1995/pair

Integrated:
Rogue Cronus- 100w, $2395
Any others?

I'm open to any other options you may know of. Also, if there's any insight or positive experiences with matching pre/power amp please share. I'm new to tubes so I have a lot to learn.

@hilde45 More tubes are used for the power supply in my preamps, being both tube rectified and tube regulated- the two 12A_7 tubes do the stage amplification and buffer job. A tube rectifier is smoother than diodes as there's no diode switching occurring, and instead of using an IC-based "chip" regulator, I use gas-charged neon tubes which were used in lab equipment before solid state was invented. The 5U4GB rectifier will last a good long time (up to 5 years for the NOS tubes) as they're only being used at about 5% of their capacity. The same goes for the regulators, but regulators are a cheaper tube, so they may fail after a couple of years respectively. All of this helps provide a very organic and smooth sounding power supply, and in tube-based gear, all of this is audible as the signal rides on the high voltage supply. Typically good NOS rectifiers run $10-$15 and the OD3 regulators are about the same per pair. Best regards, Aric
@aric Wow, thanks so much for that explanation. That would totally put my mind at ease about the number of tubes issue. If I had not made a choice on my amps already, I'd be ringing your phone!

Aric, please provide measurements that show SS diode noise in a tube amplifier output.

Tube rectifiers have a sound that some enjoy. Others think it mushy.

Diode switching noise is around 12MHz and tanked in the filter caps.

Tube rectifiers have slower transient response and sag voltage when called upon for more current. Many power amps with tube rectifiers should have two.
