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.
11-19-09: Fmpnd Thanks Kgproperties! You and I must have similar tastes. Your description of the Tungsram sound is exactly what I told Darren yesterday. I reviewed the original version of the AMR for Stereo Times and just had Darren send me the .01 update (with Tungsrams). I still have both players.
I am having a hard time finding the RFT EZ-80s. I have a friend loaning me some Telefunken EZ-80s and Bendix 6900s to try. It sounds like the RFTs may be what I am looking for from your description. Do you have any sources for the RFT EZ80s?
Here is what I learned about the EZ81 as a drop-in for the EZ80. The EZ81q is pin-compatible but draws nearly twice the heater current (1.0A vs. 0.6A). I am not sure if the transformers in the AMR have enough capacity to take the EZ81 but I will try to find out. Fmpnd (Threads | Answers | This Thread)
11-26-09: Fmpnd 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! Fmpnd (Threads | Answers | This Thread)
