Preferred Series 5AR4
This 5AR4/GZ34 tube is the perfect replacement for any vintage or new guitar amp. It has very little sag and will keep things tight. In hifi preamps and amplifiers it will keep the low end better detailed and defined.
The Preferred Series 5AR4 construction features:
- Grey plates
- Single halo-style getter
- The filament used is low-noise
- The bottle is made with a heavy gauge glass
- And finally the bluecolor base is a nice touch too!
The Preferred Series 5AR4 tubes carry a 6 month extended warranty.

Ratings & Reviews
One year of strong service so far.
by Douglas Robertson
I've been driving this Preferred Series 5AR4 in an Allen Accomplice (Deluxe Reverb) for almost 12 months so far, and it's held up great. Voltages haven't drifted by more than 0.8 volts in that time, which is a very good sign. It still looks new even after around 500 hours of use. I'm very confident in this tube. Well done, Tube Store!

Found my rectifier...strong solid performer...I think im hooked
This is my pick for the best modern GZ34 being made at this time!
Best modern production GZ34 being made at this time, and The Tube Store, stands behind these, which is nice. I doubt it is a coincidence that The Tube Store selected the same GZ34 that I did. Those rehashed resurrected old brand name GZ34s are glorified Sovteks, with scalloped plates. The plates have the usual slight mismatch due to the way the tubes are wired internally, and it is consistent with good NOS GZ34s, or NOS Sylvania, or GE 5AR4s, Japanese Matsushitas, Mullard, Philips, Telefunken, etc. FYI, Genalex never made a GZ34. Nyquist noise is low, along with induced hum. These also last the longest of the modern GZ34s I have tried, barring NOS. Testers in use, regulated Triplett 3444 & 3444A, Hickock 15750L1, 752 & 752 A, Tektronix 576 curve tracer, with regulated screen & heater supplies, and a Tektronix 371B for transmitter tubes.
A true sonic upgrade
I purchased 2 preferred series 5Ar4 rectifier tubes for my Primaluna Dialogue Premium preamp.Have used Sovtek, Gold Lion, Mullard,PL silver label-stock tubes-,Sino in the past.With only 20 hours on them, these Preferred Series blow away the others iv'e listed. The bass is accurate & tight, the midrange is very clean & neutral, and the top end is smooth without giving up any detail, without fatigue or brightness. Best new production rectifier I've heard by far & will only get better with more playing time.Very solid, weighty tube, no thin glass or junk pins. The 6 month warranty is the best iv'e seen,price is right,- I got them during the Black Friday sale-but even at normal cost a real quality, great sounding tube.YES,different brand rectifiers make a big difference, I can easily hear the differences.Best one, so far!
