Suitable 5AR4 for Vox AC-30?

[Mark]

I have to put a rectifier tube into an AC-30 and I'm curious as to which brand of 5AR4 or gz-34 have you guys found to be robust enough to handle the AC-30?

I would like to stipulate only new production valves, the NOS option is too expense to consider.

Thanks for your help.

Well, I've had both JJ and Sovtek go south on me (in a Deluxe Reverb), so I think it's a crap shoot with current production tubes. That said, if size is an issue, the Sovtek is smaller. Otherwise, I believe the JJ follows the original performance curves a little better. Don't know anything about the Chinese versions.

I have had luck with a chinese GZ34 in my superreverb. Great sounding....I tested several batches sovtek's ( I did not like these at all) and this chinese tube held up tonewise against a NOS Philips Miniwatt GZ34.

I assume it is a Sino but I'm not sure.
