The Bendix 6106 is more of a 5Y3 substitute. It would not be an adequate replacement for a GZ34/5AR4. No wonder one went kablooey!

They're indirectly heated rectifiers. I also have an NOS pair of Amperex labeled Mullard GZ-34s, but I've never tried them in my amps.

Yes, 6087/5Y3WGTB.

but they're not very common. Baby brother to the GZ34.
I did more searching and found another Bendix offering, the 5852 which looks similar to what I have, at least at first glance. I found it on the site linked below. It seems to be a militarized 6X5, link to data sheet HERE
The question becomes, how do I find out exactly which tubes I have here?

I'm finding posts about them like the one linked below, from fourteen years ago where Jim McShane said:
"I've also seen them [6106] labeled 5AR4, believe it or not!"
Given the 6106 aviation rating, it's nice to know that if I ever get an amp which uses them, my rectifier will be good to 80,000 feet.
Thanks again.

About the only physical difference I can see is that the Tube Depot site says theirs has Double D getters, while the ones I have have a quad of D getters. Mine more closely match the drawing in the Bendix 6106 data sheet though.I wonder why New Sensor didn't just remove the 5AR4 stencil from the base and sell them as what they were?
"No wonder one went kablooey!" Yeah, no kidding. The voltage, combined with a first cap of 40 uF in my amp, while the 6106 data sheet says 4 uf, you're right, no wonder!
Thank you very much. I'd have probably never found that on my own. Much appreciated!

for all the 5V4s they sold cheap that were actually high quality 5AR4s. :)

Still, given what the Bendix 6106 are going for now, they may have unintentionally screwed themselves twice.
Meanwhile, I continue to be grateful to Opalize for his excellent call on identifying these tubes. I'm sure at some point I'd have put another one of these into one of my amps which use a 5AR4 "just to see what happens this time", and have been treated to another arc.
That would have had two negative results. It would have left me thinking I paid good money (back when I had very little) for 'shitty' 5AR4s, and it would have destroyed three good Bendix 6106 in the process.
Actually, not sure it was New Sensor, but there was a batch of 5AR4 (Sylvania?) that were sold cheap because of this. I think the episode goes back about 10 or 15 years.

...the 5V4s that where actually Sylvania 5AR4s (Phillips ECG actually) were quickly discovered and publicized fairly widely. Dealers like Triode Electronics bought them up in bulk and sold them for pretty much the going price for US mfg 5AR4s at the time. My best finds came at hamfests where sellers didn't know what they had. But they learned quickly.
Your tubes are 5V4.
