Alternative to 12AX7-EH tube needed...new to tubes


I purchased a new to me preamp a couple of weeks ago and would like to replace the tubes. I am a first time tube owner and would appreciate any and all advice. It's an Aronov and is connected to a McIntosh 752.

I would like to lower my noise floor and reduce how hot the signal is on my preamp out. Basically, I want to be able to turn the gain on my amp back up.

Would a Sovtek 5751 be a good alternative?

I want to keep my highs detailed, lows fat, and the mids rich and full.

Thanks.
