I now have an Ayon Crossfire III that uses a 5U4G rectifier for the input and driver tubes. I am currently using a NOS Svetlana "Winged C" that sounds good and seems to be well balanced.
The question is, what is significantly better than this one (I also have a NOS Sylvania 5U4GB that I haven't tried yet) from the NOS world that is not "unobtainium" or outrageous priced. How would this compare to new made ones from Emission Labs, China, Ayon (rebadged EML?), KR Audio, Sophia electric etc.
I have a chance to get the Ayon mesh plate ones that are absolutely HUGE compared to the typical NOS 5U4G. They look more like a big output tube.
I will be giving a trial on those because I am currently reviewing the Ayon Vulcan Evo monos that are using this beastly 5U4G.
I have not really done a lot of rectifier rolling tube it made a big difference in a Lampizator DAC trial I was a part of a month ago. Also, it made a pretty big difference with a PureSound A30 amp that I had.

Anyone tried subbing the 5U4G with VU71?

Timely thread. Need one for a new (to me) pr-amp.
The manufacturer recommends Sophia Meshplate 274B - $200.
There's a couple of new caps installed that I want to burn in w something a little less expensive. I'll want a back up anyway.
I second the Tung Sol 5U4GB top getter. It is as good as the RCA 5U4G in a smaller package.

Almost any American-made 5U4G tube should do fine.

Congrats on your new amp. In general I had good success with Ken Rad VT244.
After rolling a bunch of vintage American 5U4Gs (and not any of the new production offerings or ultra-expensive vintage variants), I remained with the Tung-Sol 5U4G with top getter -- which turns out to be often recommended today. I don't know current pricing, but something tells me it will be affordable relative to the value of that amplifier.

U52. Be prepared to pay $500 or more for each.
There is also the VT244, which I think was a military version of the 5U4G, put out by US tube mfrs. I prefer KenRad and RCA
The simple RCA 5U4G sounded great to my ears.
Another one that is rated among the best. You need to watch the value of your C1 if not a choke loaded power supply
