I need more gain out of the phono amp I built and am exploring the SUT route. I have a Dynavector DV20X2H cartridge.
Output 2.8mv
Impedance 150Ω
Recommended load >1000Ω
From the reading I have done and I'll admit I don't have a comfortable amount of understanding but it seems like I would want to increase the output to roughly 5mv to put it on par with most MM carts. What ratio SUT do I want? 1:2?
Then to get my 1000 loading parallel the 47000 with a 5.1k resistor which is divided by 4 the square of my ratio.
These numbers seem a bit extreme. Is the output of my cart too high to use a SUT?
I also posted about raising the gain of my amp. Maybe if thats possible would be a better solution?

I an running a 300B SET amp with autoformer volume controls. No linestage. Phono amp is the ANK L3 phono kit, I don't need a ton of gain. Say 1/4 of my volume knob would get me back where I want to be. I know this cart is suppose to work with a MM input but then again they made the output 1/2 the level of most MM carts.

So you have enough system gain, but only if you turn the knob “further” than you’d desire?
Eh. In that circuit things would get pretty messed up. Go back to the SUT idea.

as the tube ages, r(A) changes so the compliance to the RIAA curve will change from optimal.
Seriously? With a 270k resistor?
VAS in NJ did it. I moved to PA from Oregon and my stylus didn't make the trip. When it arrived it was missing. The cantilever broke due to the extreme cold weather and riding in a truck. He did it fast for like $400 if I recall correctly. I couldn't believe the improvement the boron made. It was a major upgrade in the sound. He did it fast too. His shop was packed FULL of gear to die for. I didn't want to leave..
