Any experience with EZ-80s, 5687s or Bendix 6900s?


I have an AMR CDP and it uses EZ-80s as rectifiers and 5687s in the output stage. I may have a problem with a rectifier tube and was thinking of replacing it (them). I know nothing about EZ-80s (or EZ-81s). The current rectifier is an NOS Philips. Does anyone here know what a Telefunken EZ-80 might sound like in this application or how it might compare to the Philips?

Also, I have heard that some people are using Bendix 6900s in place of the 5687 Tunsgarams. Same questions here if you have any input.

Thanks,

Frank

Thanks Kgproperties. I just bought the RFTs from him and they shipped yesterday. I also found an NOS set of Bendix Gold pin 6900s from a dealer and bought them. I'll keep you posted. I hope I get the same great results you did.!! ENJOY!
I use the 5687 Raytheon Cryo-Treated, not bad for the Sonics, tried the tungsol 5687 to warm for me...
Looking for the 'Bendix 6900 Red Bank'???
Glory, I've been away for quite a while and just happened to be researching tubes for my AMR again and saw your post. The Bendix were wonderful for a couple of months and then just crapped out on me.

I do not know if I was purposely sold old or defective tubes at the time (even though they were represented to me as NOS) or not. However, based upon subsequent dealings with that same dealer. I now consider him to be fundamentally dishonest.

Thus, I am now not sure if the tubes I had were representative of what an NOS Bendix really has to offer.

I am now open to suggestion as the AMR distributor screwed my player up when he upgraded it by taking out my double crown chip and never replacing it . Between that and the tube issues, I have never been able to get the real magic back with my AMR that it used to have. I now use it mainly for headphones and have since gone back to my Reimyo as my main CDP.

Hard for the B6900 to crap out. They run forever. Send them to me I will take them.
