audio research REF2 MK2 5AR4 / GZ34 problems

Has anyone had issues with their REF2 going through the recitifier tube fairly quickly?

I bought the unit used a few years ago, seems like this tube is allways the one that goes. I have tried the stock Sovtech and JJ GZ34. The JJ held up the best ( 7 months or so )

When I purchased the unit it had a Ruby tube in this spot. Of all the tubes that one seemed the most robust... until last night!

Back to a stock Sovtech I just purchased for now.

Thanks for any advice you can offer.

Rectifiers should last a really long time. Even if you left you amp powered on for 7 months straight, the output tubes would fail long before the rectifiers.
My guess, you have something wrong in there. I'd start by contacting AR or spending the money having a tech check it out. Simply put, this shouldn't be,even with cheapo sovteks.
