Looking closer I notice they have multiple ratings. For example it says 120v input, but 10 watt. So is that still too small for 12 watt amp?

With the amp straight into the wall, the volume knob has to stay on 0 to not blow my neighbors away. But if I starve the amps power with a variac, I might be able to push the tubes a lot harder without a big loudness increase. More gain without more volume.

Can we see a picture of that? I've never seen an amp where the speaker connection wasn't either a 1/4" jack or a speakon jack.

Ya I agree with @mozz. A 1 amp or greater would probably be fine. These do exist but you would be searching on eBay for a used unit. I’ve seen as small as 1.25 and 1.75 amp units by Staco that look fairly compact. I’ve also seen 300va Chinese made units that claim 3 amps but if you work the math out at the 130 volts they can work to, it’s really 2.3 amps. The Chinese manufacturers fudge the ratings. If you take a look at the old school variacs; when they say 0-140 at 10 amps, they can handle 1400va.

Here’s an idea for you but make sure you read the listing and agree to the terms. Ymmv.

Gotcha, thanks! Now that I understand it's hard-wired in, it makes a lot more sense.

YES.

I was looking at some old pieces going, gee if I'm playing with fire should I at least have a decent grounding...

Okay well, I'm still gonna go digital then. The non digital ones can be a lot more than +/- 5% out of spec.
