Mullard GZ34 / 5AR4 Rectifier Vacuum Tube
The classic Mullard GZ34 rectifier tube has always been a favorite and is the most sought after version. The reissue is now available with the same great performance without the high price that NOS Mullard GZ34 vacuum tubes command.
GZ34 is the European name for the 5AR4 and is compatible with any circuit using a 5AR4 tube.

Great audio rectifier!
by JD
I use this in my Line Magnetic 518ia audio integrated amp. Combined with a new pair of drivers the overall sound is smother, tighter (more grip on bottom end), and with better resolution. Gone is the stock tube's tendency to sound glassy and boomy.
