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

Brian Kyle of Xtreme AV in southern California sent you the Bendix 6900s on good faith that you would send him the money for them. I understand they were good and strong when he had them, yet only now the performance of the tubes is brought up. That aside, Brian contracted brain cancer not quite 3 years ago -- long after he sent the tubes, and his condition has deteriorated drastically to the point that he is now on daily hospice care, is unable to stand and walk, and may not be alive a month from now. So now "subsequent dealings" with him -- of which there were none -- and his integrity ("fundamentally dishonest") are called into question. Brian is incapable of defending himself due to his condition.

Did you purchase the Double Crown DAC chip from the distributor, whose reputation you impugn? What upgrades were performed? Any repairs? Where, and who paid for them and shipping?

People reading this can draw their own conclusions about ethics and integrity.
Apologies are very much called for by the two posts after mine. I also asked questions about your strong accusations of the distributor stealing "your" DAC chip and screwing up your player. Add to that the kicking of someone while he's down (permanently) while giving no proof of wrongdoing. And by your own admission you used tubes not approved for the player without checking, which likely may have "screwed up" your player -- not something covered by warranty. Fmpnd, it's time for you to man up, tell it like it is and accept responsibility, and make amends with the two people you have victimized, including a public apology here.
