The Sovtek 5AR4 (GZ34) Rectifier is a suitable replacement for any 5AR4 rectifier tube.
Sovtek 5AR4 rectifier tubes are robust and work great in many different guitar amps such as Fender 40W and Vox AC-30 amplifiers. The Sovtek 5AR4 rectifier has a rise time from 300-400 volts that is about half that of a 5U4 tube.
These rectifiers are well made, will last a long time and are a cost effective alternative to increasing NOS prices.

The Classic valve amp rectifier used in the early Marshall and many American made amplifiers. This valve features in the treasured JTM 45 amp and 1962 Bluesbreaker combo and is an essential part of the origin of classic tone for which there is no substitute.
For amplifiers modified away from the GZ34 to accept solid-state rectification, a tech may be able to retro fit the GZ34 to retrieve the lost original sound.
