I purchased this tube (GZ34S) in for use in a Dynaco ST-70 I rebuilt. It worked great for about 5 weeks then I accidentally hot switched the amp and the rectifier promptly flashed over internally. Yes, this is my fault but upon examination of the tube under the magnifier the cathode and plate connections on one side were just too close to each other.

I rated the tube a 3-star for product construction, perhaps this is too harsh but darn it...

On the other hand, I am very happy this was only a $15.00 tube! I would buy it again, especially for trying out new constructions and first time power up.

I must agree with others who used these rectifiers. The price is right and you get more for your money than other choices. I am using them in a pre-amplifier that used 27's and 8 red LEDs for cathode bias and outputs to a 245 amplifier via 10K interstage transformer and I think they contribute to the smooth sound this gives me.

The JJ GZ34 has a lower voltage drop than most 5AR4 tubes. Very good value for the money.

I re-tubed a modified Fender Deluxe that was becoming noisy. I gig a lot and it had been awhile since the tubes were replaced. With the new tubes the amp is much quieter. Thanks.

I've learned that the total tone characteristics is changed by using different rectifier.
SOVTEK gives me darker color. And This JJ gives me more highs which leads brighter color of tone.
Reliability is almost the same as Russian one but better than Chinese ones.
