This power tube (for my Fender Princeton amp) is quite hard to find in the Philippines. It arrived in good condition and worked! Thanks Amazon.

I used this for the first time while fixing a couple old Dynaco ST70 amps. These tubes gave me lightning in both amps. Probably less than 1 hour total time on that tube. Pulled it out and ordered a recommend tube. The boards that deal in vintage tube audio poo-poo this tube. So no more for me. The recommended tube was a TAD. I've been running the TAD for a couple of hours now and no issues.In addition the tube is under warranty. I contacted JJ with the concern, and they offered me to send it back. Since shipping would be roughly the cost of the tube I am going to decline. I don't suspect the warranty would be any different with tube from China or Russia so the consumer option from a fiscal standpoint is any issue that happens with a product, using that same vendors product again should be assumed to be at your own risk. For me, thank goodness I have plenty older good quality US/Euro tubes. I just don't have any GZ34's, BUT I will not buy tubes from JJ anymore. I realize this could have been a fluke and the industry of tubes is not huge anymore so having a precence in every country is not viable, but they are not cheap either.

Got it here quickly in good condition at a reasonable price. Probably should have bought a backup as well. Once again the curse of the AC30 CC2 standby

These vacuum tubes came well packaged and quickly. They appear to be brand new (I have not used them yet). I would not hesitate buying from this seller again.

I bought this rectifier to replace a solid state unit installed in a used Vox Ac30 I acquired. While subtle, it has some influence on the tone when pushing the Power Tube circuit. Love the result and it brings the AC 30 back to rectory spec.

Glad this tube (5ar4) was available and at a reasonable price. Some dealers are asking $75.00 or more for tubes today. The Fender amplifier I have is in demand and it should be able to be repaired at a reasonable cost. I purchased filter capacitors for this amplifier also from Tube Depot. They were also reasonably priced. My 1963 amplifier works like new. The orders came promptly without any errors.

Got this as a replacement rectifier for my silverface Fender Princeton when the original tube started acting up - needed it for a session a few days later and the JJ tube worked out great, and continues to function without problems. Nice replacement tube for a nice price.
