Rectifier Tube question

[Roadster_08]

Hey guys, just a quick question. I should be safe to run a set of sovtek 5ar4's in my roadster in place of the 5u4gb's, correct? Depending on my findings i'll pull the trigger on some nice mullard's in the near future

I wouldnt try comparing the Sovtek to a Mullard.The Sovtek is crap compared to a Mullard 5AR4. A 5AR4 should work with no problem in that amp,the AR4 will be somewhat "tighter",but the difference is so slight you may not even notice.

Apart from the fact that Sovtek 5AR4s are some of the most unreliable tubes ever made, yes it should be fine.
