A less powerful amp is recommended; here's why:

Posted by Ralph on February 24, 2017 at 10:15:51:
In most push-pull amps, the distortion is a certain amount at full power. As you decrease the power, the distortion goes down to a point about 5% or so of full power. At that point the distortion often increases, and it can be by quite a lot!

And you have efficient speakers, so the ARC is going to be operating about 95% of the time in this higher distortion range! So you won't be hearing the best of the amplifier by any means.

The solution is a less powerful amplifier. You can still run push-pull, but it should be 30-60 watts in most rooms. With a single pair of output tubes it will be less distortion as well.

Whatever your SET amp was for power, I would get a push-pull amp of about 4 times the power of the SET. I think you will find that to work quite nicely and you may find that it sounds a lot better.

I suspect that is not a lot of power so you might be able to find a triode amp to fit the bill. Might as well make the most of it...
